Dude, Where's My Car? (2000)

Other mistake: When Chester is taking Jacko's pipe, Nelson gets up out of his seat. When they show Jacko really really mad, you can look in the background and Nelson is sitting down. When they show him again he is out of his seat.

Mr. Pizzacoli: A trained dolphin could deliver pizzas better than you two!
Jesse: But then the pizzas would get all wet.

Trivia: After changing into the bubble wrap outfits or "interstellar jumpsuits," an alarm goes off. Jesse turns and hits Chester in the eye accidentally, and you see him fall if you watch closely.
