When Von Zipper falls through Sugar Kane's window, the rest of the bikers suddenly appear behind him in the next shot.

When Frankie takes his first jump from the airplane he is wearing a red helmet. The first shot of him leaving the airplane shows a jumper with a white helmet then back to a red helmet.

As Buster Keaton chases the beach girl along the shore, the number of rows of footprints in the sand varies from shot to shot.

When Eric Von Zipper crashes into the club and lands head first in the aquarium of gold fish, the view from inside looking out, shows a street scene with buildings and exterior stairs, but moments before the view outside is of a parking lot and the beach.

In the pool hall fight scene, Von Zipper has a yellow pool ball in his mouth. However, when he spits it out and it hits two other balls, the color has changed to red.

Frankie and Dee Dee free-fall their first time sky-diving. In real life, the first time people sky-dive, their parachutes are set to open automatically when they jump from the plane -- this is because some people faint their first time sky-diving. And if they are unconscious, they can't open their chutes, and they will crash into the ground.

When the gang is dancing at Sugar's, Animal stops dancing and turns toward the direction the Rats will come from several seconds before they actually do.

When Bullets asks Bonehead if he lives in a cave, Butch can be heard saying "You're close" but his lips don't move.

Frankie can be clearly seen waiting for his cue behind the attic window of the "bubbie house" before he finally jumps through it and punches South Dakota Slim.

In the airplane, when they are about to skydive, Frankie says to Dee Dee, "First one down's a rotten skydiver." This is wrong. The first one down is the one who did a "free-fall" longer, and is a good skydiver. The last one down is the one who chickened out, and opened their parachute too soon, and is a rotten skydiver.
