* The sight of Elijah Wood [[http://www.youtube.com/watch?v=3OPuUUa4e1s&feature=related laughing in a high-pitched voice]] (at about 7:20) during the drug test scene.
* The entire group erupting into panic once [[spoiler:Delilah reveals herself as an infected]], with all the guys trying to will themselves into shooting her. And then Stokely bursts through the crowd and goes "I'll [[PrecisionFStrike fuckin']] shoot her!" and fires about five bullets in [[spoiler:Delilah's]] general direction.
* While it's MoodWhiplash, when the coach [[spoiler:stabs the principal with a pencil]] he says, "I've always wanted to do that." [[spoiler:The principal]] thinks she's made it to safety, locking him inside, another teacher stabs her repeatedly with a pair of scissors, and then says, "I've always wanted to do that."
