Continuity mistake: During the first scene at the disco, closely watch the two Asian girls. Right at the beginning of the scene, they are off to the right, dancing about a yard apart. Immediately in the next shot, they are standing right beside each other.

Continuity mistake: When Vilmer lights the girl's back on fire as she's passed out at the table, she gets up and starts stumbling towards a wall covered in keys. As she stands up, there is no visible fire on her back. In the next shot as she is up against the wall, her back is on fire again. (01:06:25)

Continuity mistake: In the final scene, in the bathtub with Stifler's Mom, the amount of soap bubbles on Finch's head changes between shots. (01:33:40)

Continuity mistake: During the scene when Gaylord Focker enters the room, while Bernie and Roz have fun with whipped cream, notice the whip cream on Bernie's face. Although the amount of cream would change because Bernie wipes his face, the amount and location of the whipped cream changes, goes back, changes again, and is almost completely different in each shot. Once wiped away, it is highly unlikely that whipped cream would magically reappear in the exact same spot as before, and then disappear again. (00:48:25)
