Continuity mistake: When Dr. Sawyer is giving Kris the exam, during the part where Kris is doing the physical coordination test, we see Kris from Sawyer's point of view, and Sawyer is drumming his fingers. When the shot switches to Kris's, he is fingering his eyebrow. When it switches back, fingers drumming. Finally, when it switches back again, his hands are neatly folded in front of him.
Continuity mistake: Pinkie sweeps all the glasses on top of the bar onto the floor, yet after he and his gang have gone we see broken glass on the bar top.
Continuity mistake: Lulu gets out of bed and races to the bathroom to "Brush her teeth." She picks up a tube of toothpaste and a toothbrush, then proceeds to brush her reflection's teeth in the mirror. She does not set down the toothpaste, and when the angle changes as she washes her face, the toothpaste has vanished, not in her hand, not on the sink. (00:01:20)
Continuity mistake: When Jerry opens the door of the refrigerator, there is a piece of corn on the cob on a plate and next to it is a bowl of eggs. In the next shot, the eggs have become fruit.
Continuity mistake: When Jerry hides from the Tom in the bottle of invisible ink, the two test tubes on the right hand side contain red and yellow liquid, respectively. When Jerry emerges from the bottle, the liquids are now purple and blue.
Continuity mistake: When the cat places the tiny canary on to the plate, the salt and pepper pots on the table change positions between shots, and the cabinets in the background disappear. He also has a knife and fork in his hands, but after the canary says he's been sick, we return to the cat and the knife and fork have disappeared.
Continuity mistake: When Tom is tip-toeing past the gate at the start of the cartoon, Spike is sleeping and you can see there is nothing around his neck, but in the next shot a dog collar has suddenly appeared.
Continuity mistake: When the mouse pulls the lion's tail in the jungle, there is a tree in the background. When the camera closes in on the mouse in the next shot, the tree has gone, and in the shot after that, it is back again.
Continuity mistake: Bob Hope asks to take a peek at the execution chamber. He peeps from the hole, nudging away the lid with his forehead, and turns away. The lid came to a complete stop, but in the next shot when Ronnie walks away here's the lid swaying again as if he had moved his head from the window just that moment. (00:02:25)
Continuity mistake: When Butch points his pistol at Tom, you can see that the handle has nothing written on it, but in the next shot the words "Ajax" have appeared.
Continuity mistake: When Robert Taylor escapes from the asylum, and is driving the second car he steals, the car is shown at least once with windshield wipers pivoting from above the windshield, then shown with the wipers pivoting from below the windshield. Clearly, these are two different cars. I think the studio borrowed wiper footage from the scene in which he is driving the first stolen car, to use at moments in the scene in which he is driving in the second car.
