Little things that crack you up.
There are a lot of little things about this movie that make it hilarious. For example:
The grilled cheese sandwiches that Missy made were totally burned and looked disgusting!
The way Ted's dad ran after Bill's dad on the way into the auditorium while saying, "He's going to an Alaskan military school!"
How about that gnarly old goat dude?
Anybody have more?
