Revealing mistake: When Dewey is singing the protest song about midgets in 1966, modern cars can be seen driving in the background.

Continuity mistake: Near the end, when Lucy tries to get into the building, she is blocked by police officers holding clubs straight ahead in front of them. The scene cuts to a roof shot, then back again, and Lucy tries again, but the clubs are missing, the cops just have their hands out in front of them.
Continuity mistake: In the shot just before Jules' friend asks, "Can you get us booze?" Seth's collar is folded inwards. In the shot just afterward, it's unfolded, partially obscuring the strap on his bag.
Other mistake: In the sequence where Bo is taking his driving test, the driving instructor is shown fumbling to put on his seatbelt three times, all of which are from the same piece of film. (00:00:45 - 00:02:45)

Continuity mistake: In the scene where Randy is playing table tennis on the stage at the restaurant, just after he has finished hitting the ball blindfolded and says, "Thank you", you can see a man in the background getting up. The shot then switches to the boy with the man in the background still sitting. The shot then switches back to Randy and the man is getting up again.
Continuity mistake: The whole time Dan is in the bookstore and outside talking to Marie, he is wearing a blue undershirt. However on his way home from the bookstore, he runs a stop sign. When the cop comes up behind him you can see that his undershirt is now grey. When he gets home and walks through the door, his shirt has gone back to blue. So Dan's shirt changes a few times when everything is supposed to be in the same sequence of time and events.
Continuity mistake: In the shower scene where the soaps are dropped, what Larry is holding changes constantly. He goes from holding a white tube of something, to holding what appears to be a green shampoo bottle, to digging in a zippered case with his stuff in it, back and forth and around, several times.
