I already have a list of movie lines that always make me laugh...and here's part 2. You can find part one at this link
1. "You've got a mustache." "I know!"
2. "Medium is really only for suckers who don't know the concept of value."
3. "Rodents of Unusual Size? I don't think they exist.."
4. What, so I got to sit here and eat dessert alone like I'm fuckin' Steven Glansberg?
5. Why don't you go back to your home on Whore Island?
6. "How would you like to suck my balls, Mr. Garrison?"
7."Mr. Treehorn treats objects like women, man"
