When Velma sneaks off to follow Mr. Crunch, Freddy organizes a search for her. He should've simply turned around, because in the very next shot she is right there behind him.

The Dynamic Scooby-Doo Affair (Batman and Robin)

Robin changes height several times throughout the episode.

The gang hears someone approaching the house and everybody runs to hide, Freddy, Daphne and Velma behind the crate. If the mysterious person turns out to be the criminal, which is certainly possible, behind the crate is the worst place to be, as it's pretty likely he would be coming to check on his crate.

Shaggy's beard is missing.

The blindfolded Shaggy pulls Scooby over the car seat like he can see him. Is he peeking?

Batman says they can't use the batrope to escape from the pit trap because there's nothing for it to grab onto, not even a doorknob. Actually, there is a doorknob plainly visible in several shots.

The Joker pulls the exact same lever for different spooky effects.

Velma is a better detective than Batman; she's the first to notice that the Batmobile is missing.

Robin loses his emblem.

Batman's throat is colored blue a few times.

Lots of people manage to talk without moving their lips: Fred, Robin, Batman and the Joker.

Scooby leaps through a broken window that is half obscured by jagged glass, miraculously, without cutting himself.

Shaggy jumps into the front seat of the car but is soon seen in the back. Did he climb back there to be closer to Scoob?

The crook should've seen Freddy coming into the crane, yet the teen manages to sneak up behind him.

Freddy lies about what happened inside the crane. Perhaps he was ashamed to be so easily overpowered by the diminuitive villain.

And just how did that little old lady Mrs. Baker take out big, strapping Fred?

The rims of Velma's glasses turn white.

When Shaggy and Scooby are on the moving floor, the door in front of them is sometimes there, sometimes gone.

For some reason Batman temporarily removes his gloves not once, but three times throughout the episode. Robin also loses his gloves once.

Daphne rides a bicycle very well, although in Bedlam in the Bigtop, Shaggy says that she can't.

The Joker's closed circuit TV sometimes shows people without the background.

Scooby loses his spots for a moment.

In the warehouse, Batman warns the gang that there are piles of crates ahead. He fails to mention that there are also piles of crates behind them and on either side. In fact, the room is filled with piles of crates.

A toy punch clown knocks Velma one way and her glasses in the opposite direction. An instant later, we see the glasses right next to her.

When Robin enters the mysterious house, he comments that Shaggy was right and the furniture is indeed nailed to the floor. Only it was Freddy who made the comment about the furniture.

Are the pillow and blankets nailed to the bed, too?

Wednesday Is Missing (The Addams Family)

Why does the gang think the very obvious headlights are giant eyes? Even the ever-practical Velma is scared.

Scooby loses his spots several times throughout the episode.

The Mystery Machine vanishes from one scene, but its tire tracks are still there.

The gang has seen the Addams Family on TV...in what, a documentary?

Morticia is standing in front of Gomez at the sandbox, but somehow her arm goes behind him.

Daphne loses the stripe on her skirt.

Fester's trapdoor doesn't close correctly.

Look at the dishes on the table. In the far shots, they don't seem to be drawn or painted, just formless white patches on the table cloth.

Although he is shown quaking in terror at the flapping sound, a moment later Shaggy is seen sitting at the table smiling away.

It sure seems like the vulture is actually in the dining room, which would be pretty tough for a helicopter.

The candles on the table are out immediately after Thing lights them.

Grandmama and Uncle Fester aren't very concerned about Wenesday's disappearance; at least, they don't help to look for her.

Frickert Fracas (Jonathan Winters)

Freddy forgets to open his mouth while talking to Jonathan Winters at the gas station.

The scarecrow pops up from behind a barrel, but he wasn't there a second before.

Shaggy goes aroung the mill wheel head first, except when seen through the window, when he passes feet first.

At the end of the episode, Shaggy laughs but we only hear Daphne.

Guess Who's Knott Coming to Dinner (Don Knotts)

From our vantage point outside the house, we see Don Knotts move past the first and last in a series of windows, although we never see him in the middle windows.

When Scooby falls down the chimney, it scares him spotless, for a few seconds, anyway.

Is Daphne mocking Velma when she speaks in a perfect imitation of her voice?

We know that Phineas Fo'c'stle's peg leg is a fake, but is that any reason for him to wear it on different legs at different times?

When Scooby puts a banana on top of his sandwich, his paw is momentarily peach-colored instead of brown making it look more like a human hand than a paw.

While running from the ghost, Shaggy bursts through the bedroom door, flattening Scooby between the door and the wall, then slams the door to keep the ghost out. We then see Scoob, still splatted against the wall, but the door is open again.

The gang finally finds Capt. Moody tied up in the old mine. Although they were standing only a few feet away from him for some time talking, the captain never once called out for help.

A Good Medium Is Rare (Phyllis Diller)

Shaggy and Scooby slide down a laundry chute and land in a basket. A moment later, we see Shaggy and Daphne in the same basket while Scooby has one all to himself.

Sandy Duncan's Jekyll and Hydes

Although Scooby is in the back of the Mystery Machine, he is somehow in front of the seat at the same time.

One of the flower decals is missing from the Mystery Machine.

Although it's night, the background shows a daytime sky at one point.

Scooby loses his spots several times in this episode, and once they run together into one big blotch.

The fallen lamppost vanishes, but soon returns.

When Scooby acts out the man pulling down the lamppost, the gang acts like they never saw the rope. Say, what happened to that rope, anyway?

Shaggy says the overhead door won't give, but he and Scoob are just barely tapping on it; they look like they're not even trying.

When Scooby bangs his head on the manhole cover, a woodgrain design appears on it. Then, it is suddenly on the ground next to the hole. But when Shag and Scooby jump out, both hole and cover are gone.

Both Daphne and Velma suddenly find themselves wearing watches.

The sheikh seems to appear suddenly inside Scooby's cloud of sand.

We know that can't be a coin slot in an Egyptian sarcophagus, not even in a phony prop, but then, what is it?

The ski lift is entirely different in different shots.

Fairchild, as the mummy, manages to get in front of Shaggy and Scooby awfully fast, and changes his costume to boot.

The dune buggy changes shape when Shaggy and Scooby exit the pyramid.

The pirate throws a net at Freddy and Daphne, but misses by a mile, until they turn and run toward where the net is falling; then they are nearly snared.

In one scene, the pirate ship has the wrong background, making it look like a dock and not a ship at all.

The Secret of Shark Island (Sonny and Cher)

Velma hardly ever has freckles for this entire episode.

Freddy wants to surf during a thunderstorm? Not too smart.

While Sonny and Cher ride in the Mystery Machine, we still see the rain pouring down, no matter how close the close-up is, which makes it look like it's raining inside the van.

Not only does the brochure misrepresent the Hideaway Hotel, it also misspells the name.

Sonny doesn't move his mouth to say "twins."

Although Cher is standing in front of the fireplace, it vanishes in her close-ups.

Cher's eyes vanish for a second while watching Matilda.

Why doesn't Meekly warn the kids about the high tide? They would've rushed right back to the mainland. Does he want potential snoopers to be trapped on the island to possibly learn about his gold-smelting operation?

The lobby desk changes color.

Shaggy doesn't move his lips when the Pescado Diabolical is shaking the boat.

The footprints by the desk weren't there a moment before.

The footprints go down the stairs but away from the desk. What'd he do, back into the desk before going down?

Shaggy comments on the "little elevator we rode in last night." That must be in the deleted scenes, because we sure didn't see that in the show.

The cellar floor behind Sonny is the wrong color.

The Spooky Fog (Don Knotts)

Shaggy actually jumps behind the mine car, but a moment later he's inside it.

Scooby loses his spots several times during this episode.

In the cave, we see a hairy brown paw push over Shaggy's rock pyramid. Who, or what, is this? The baddies are dressed in skeleton costumes.

We hear Shaggy yell while in the mine car, although his mouth doesn't move for the second and third scream; they must be echoes.

A spider web in the mine is floating, not attached to anything on one side. Is it a fake placed there by the villains for atmosphere?

The rope Don ties around his waist has three ends, one at the top of the pit, and two visible at the knot. Did it break?

Scooby-Doo Meets Laurel and Hardy

At the very beginning of the episode, Shaggy is in the front seat, but seated behind Velma, as though she is sitting on his lap. Then he is in the back, then in the front again.

Shaggy is suddenly seen wearing his shirt, instead of the pajamas he had on a moment before.

Shaggy says he won't put on his skis until he reaches the top of the hill. In the next scene, he's shown wearing his skis on the chairlift, but without them again when he reaches the top.

Freddy and Hardy see a sheet standing in the middle of the room with Bigfoot's toe sticking out the bottom. When they tackle it, they find it's only Stan Laurel under the sheet. How could Bigfoot sneak out from under it with everyone standing there watching?

Scooby sneezes so hard that he shoots himself across the room and bumps into a clue, not once, but twice in a ten-minute interval! He ought to sneeze more often.

Hardy keeps switching from one bed to the other.

Velma talks without moving her lips.

Freddy says, "Look, footprints", when he'd already been following them for ten feet.

Velma says the boys room is next door and Laurel and Hardy across the hall, but it's the other way around

When Hardy sees someone on the second floor of the junkyard office, he immediately gets a ladder to climb in the window. Why didn't anyone think of trying the stairs?

Scooby follows Bigfoot's tracks, but suddenly they're gone, then back again.

When Velma looks out the bedroom window at Bigfoot, she puts her head right through the glass.

The Ghost of the Red Baron (Three Stooges)

The Ghostly Creep from the Deep (Harlem Globetrotters)

The pirate ghost looks exactly like Redbeard, only all white.

The Haunted Horseman of Hagglethorn Hall (Davey Jones)

In this episode we learn that Shaggy is allergic to hay. However, in Jeepers, It's the Creeper he finds himself trapped in a bale of hay with no noticeable ill effects. He must have remembered to take his allergy medication that day.

The gang has a hard time following the moat monster's trail, until Velma points out that his footprints would be side by side when he hopped like a frog, and staggered when, unmasked, he ran like a man. Good deduction, Velma, except we saw the moat monster run, not hop, even before he was unmasked.

The old farmer who disguises himself as the Moat Monster is quite an athlete. He hops and runs all over the cavern wearing an oxygen tank and swim fins; he also breaks off a huge stalactite with his bare hands.

The Phantom of the Country Music Hall (Jerry Reed)

The Caped Crusader Caper (Batman and Robin)

Joker and Penguin are awfully confident that Prof. Flakey will never be able to find the hidden switch that opens the secret door to the room in which he's trapped; they trip the mechanism right in front of him and just leave him there. It's a pretty safe bet that the Professor will simply keep trying until he finds it.

Loch Ness Mess (Harlem Globetrotters)

In the very beginning of the episode, the wheels on the Mystery Machine are not actually turning.

Although Granny and Dribbles are not in the episode, they do appear in the bus.

Scooby says "Curly" without moving his mouth.

Shaggy goes to bed fully dressed.

Nearly every Globetrotter has his emblem on the wrong side at least once. Not Pabs, however; he loses his entirely.

Geese appears to be in both the Mystery Machine and the Globetrotter bus at the same time.

When the gang sees the first ghost, he vanishes, but his lantern remains. When the lantern disappears, the scene goes dark, as it should. But then, everything lights up again. Why? Did Shaggy suddenly turn on the headlights?

In one far shot, either Pabs is bald, or Curly is very short.

When the ghost of Paul Revere rides by, almost every window in the house lights up in seconds, even though the occupants appear to be in only four rooms at the time.

Shaggy has an enormous stack of pancakes, at least fifty, but when Scooby eats only about a dozen, they're all gone.

It's hard to see, but it looks as if the ghosts scared the mustache right off Geese.

Curly talks just like Bobby-Joe.

Everybody runs into a closet, but when they see the ghost inside, the gang runs out, followed by the ghost. There's no sign of the Globetrotters.

Although Meadowlark admits he hasn't been scuba diving in ages, the Globetrotters just happen to have scuba gear in their bus.

When Velma runs the boat past the rock, she's towing Pabs, but Gip seems to have disappeared. He reappears a moment later, still towed by the boat.

Velma loses her freckles.

How does the monster breathe fire under water? For that matter, how does a balloon stay under water?

The Harlem Globetrotters and the girls run out of the old cabin, the ghosts slam the door behind them and shout, "There's no escape for ye!" Hmmm...it looks as though they've already escaped. Unless the ghost meant that he'd catch them eventually, but why close the door at all?

Fred says, "There goes Scooby" before the dog falls out of the boat.

When the gang catches the first two ghosts, Freddy says, "That still leaves one ghost unaccounted for--the one with the lantern." Actually, there are two different ghosts with lanterns, one of whom they caught.

The Mystery of Haunted Island (Harlem Globetrotters)

Once again, Granny and Dribbles appear in the bus although they are not in this episode.

The artists had a tough time with the Globetrotter costumes: sometimes the globe emblems are drawn incorrectly, sometimes they are on the wrong side, and sometimes they disappear completely. In addition, the zippers vanish, along with that red piece that hangs from the back collar of their sweats. The uniforms fare little better: they sometimes are missing the numbers on the back and the "H" on the front.

The flimsy floor is actually bent by bouncing a basketball on the ceiling of the room below, then snaps back to normal. What's it made of, rubber?

Scooby loses his spots a couple of times this episode.

Shaggy shakes hands with his left.

Daphne is missing the lower stripe on her skirt.

During practice, Pabs is the only one who appears in his uniform; the rest all wear warm-up suits.

Gip lifts Velma to help her abandon ship. When they reach the island safely and walk inland, he's still carrying her.

Meadowlark calls out, "Anybody in this place?" and Gip answers with a list of their names, leaving out Geese and Bobby-Joe.

The knight somehow manages to get out of his armor and force Curly into it while under the blankets. He then gets away without anyone seeing him.

The Globetrotters must've left their sneakers under the bed, because after they fall through the trapdoor into the library, they all have their shoes on again.

The villains put a lot of work in their haunted island effects to scare the Globetrotters. Since they couldn't have known that the team would meet Scooby and the gang and agree to sail to Picnic Island with them, they must've had some other plan to get the Globetrotters on that boat.

Velma says, "Look! Luminous footprints," but we don't see any.

The glowing foot and handprints were apparently left accidentally by the bad guys, just luminous paint that rubbed off. So, how did they get prints behind the books on the shelf? For that matter, why do the handprints continue outside? The villains should have finished crawling once they exited the tunnel.

Fred's collar turns white.

The Globetrotters keep falling asleep during their game, but the gang doesn't appear tired at all, although they, too, were up most of the night.

The scoreboard depicts each digit separately in its own little window until the very last scene, in which the number 15 appears in one window. On second thought, it must be a different scoreboard, one that was removed for repairs, since it appears to be sitting on the floor.

Twice, the numbers on the scoreboard spin horizontally to change instead of rotating vertically.

The Haunted Showboat (Josie and the Pussycats)

Mystery in Persia (Jeannie)

Spirited Spooked Sports Show (Tim Conway)

The Exterminator (Don Adams)

The Weird Winds of Winona (Speed Buggy)

At times, Speed Buggy loses his antenna, and once, his pupils.

Shaggy and Freddy spend the night in sleeping bags laid out side by side, but when Shag is shown a moment later, Freddy's nowhere in sight.

Daphne gives us her famous Velma impression.

All through this episode, Mark looks Hispanic, but in the Speed Buggy TV series he looked white. Perhaps he simply got a good tan.

Debbie recognizes the gang and knows them all by name although they've never met. Are they really that famous?

Speedy's a two-seater in front, but Velma manages to sit between his bucket seats.

Mark says that the girls will need to take Speed Buggy in order to get into the village, even though they all walked to the village the night before without a problem.

Mark and Debbie both lose the pocket on the front of their shirts.

Speed Buggy heated his tailpipe enough to melt a padlock to slag, yet the pipe itself was unharmed.

We hear the sound effect of Scooby sniffing even though we can see that he's not.

While inside the caves, the weird winds blow the kids away, but at one point, the girls are blown foreward instead of backward.

Why does the wind blow Tinker so slow and the other guys so fast?

Shaggy and Scooby hide in the kneehole of a desk. Somehow, they run out through the wooden panel covering the front.

Seven healthy teen-agers with a big dog and a small car continually run away from four unarmed, ordinary-looking thugs. Surely they could take 'em.

Tinker drives a skip loader but tells Debbie to hit the brakes.

According to the sign, Winona has a population of 10. But we see Mr. Duncan, the Sheriff, Mr. Peabody, six people on the sidewalk, and six cars on the street, making more than ten people.

The Sheriff calls a map of Winona a scale model.

All four villains are tied up together at the end of the episode. Somehow, Mr. Peabody frees himself and runs away although there are still four crooks tied together.

The Haunted Candy Factory (Cass Elliot)

Cass Elliott says she's thinking of changing the name of the factory to Sugar Plum, even though this is the name already on the sign on the front of the building.

The Green Globs warn the kids to leave the factory, but they stop Shaggy when he tries to exit.

Scooby-Doo briefly loses his spots.

The latch vanishes from the outside door.

Shaggy doesn't notice that he's surrounded by a giant pink bubble until he starts to float.

At various points in the episode, Shaggy sounds like both Freddy and Scooby.

Shaggy and Cass follow Scooby as the dog trails the Green Globs. When Scoob stops short at the foot of a Glob, the others are immediately behind him, yet they didn't see the villain until they were right on top of him. Were they watching the floor that closely?

When Cass can't open a sliding door, she says it's bolted to the floor. Unlikely, since it slid shut on them only moments before.

The kids and Cass are trapped in taffy when Shaggy and Scooby enter the room. Shag accidentally runs into the sticky mess as Scooby watches. In the next scene, Scooby's suddenly trapped in the taffy, too.

Piles of peanuts and other foods on the floor are serious health code violations.

The same switch on the same machine is used to work the ceiling conveyor belt and the secret door.

Some of the candy machines are very dangerous, like the jawbreaker maker that shoots candy out like bullets.

Scooby watches as Shaggy is snagged by a hook and dropped over a vat. When Freddy asks where Shaggy is, Scooby replies, "Beats me."

The Haunted Carnival (Dick Van Dyke)

Fred, Daphne, and Velma are riding through the carnival on a 3-man tandem bike. Daphne gets off and heads for the photo booth, where she and Velma have a conversation before Daph steps inside. Then Freddy comes over to ask what's going on. Where was he looking all that time?

The word "Balloons" disappears from one side of the balloon stand.

The balloons burst without a sound.

Daphne and Velma each use the wrong voices.

Scooby's nose temporarily turns brown.

Shaggy's reflection actually sticks out of the funhouse mirror.

In the tunnel, Shaggy and Scooby try to run away but a gate falls and blocks the way, forcing them to go on and find the villainous strong man. The question is, who dropped the gate? The strong man? He wanted the gang to leave, and besides, he didn't even know they were in the tunnel. Maybe he was closing it to keep them from finding his lair and accidentally locked them in.
