* BaseBreaker: Barry, who either is a wonderfully unusual side character who's strangeness balances out the more straight, raunchy road-comedy plot at the film's center, or a nonsensical creepy weirdo who has no reason to be in the movie at all and with a bizzare TrappedByMountainLions supblot that brings nothing to the table. Given the fact that he's played by [[''Film/FreddyGotFingered'' Tom Green]], it's kind of expected he'd get this reaction.
* MoralEventHorizon: Jacob was merely a creepy God-botherer until he pretended to be Josh's professor on the phone and tricked him into thinking he had an extension on the crucial midterm.
* RetroactiveRecognition: Danny Pudi a.k.a. [[Series/{{Community}} Abed]] is Arash in the sequel.
* SomeAnvilsNeedToBeDropped: Whether justified or not and clearly RuleOfFunny, this movie is still one of the most potent reminders of why you never send your diner food back to the kitchen.
