I like Wit, Exaggeration - like on cartoons, and some Slap-stick.
I think my favorite humor has to do with how things are phrased.
Charles Dickens makes me laugh even when the subject matter is by no means funny.
Often descriptions that are 'so true' make me laugh. I seem to really enjoy descriptions through comparrisons to other things
I enjoy the silly antics of Laurel & Hardy or I Love Lucy
My husband is always making silly over-dramatic expressions which make me laugh
I also enjoy understatement
Some movies that make me laugh are
The Gods Must be Crazy (If you haven't seen this, you must! the best part is with the 'anti-crist' Car)
The Hogfather (Terry Pratchet's Discworld is quite amusing - I particularly like Death playing Santa in this one)
The Great Race (Jack Lemon, Peter Falk, Tony Curtis - old fahsioned melodrama & slap-stick)
Some Like it Hot (Jack Lemon and Tony Curtis under cover as women in a ladies jazz band)
What's Up Doc (the best car chase! plenty of crazy mix ups, things going wrong, and amuzing lines - oh yeah, and it's not a cartoon)
