Please keep in mind, I'm not baiting, I'm not trying to be edgy, I'm not trying to be contrary, I just don't find them funny. Comedy is something I give a lot of leeway to just because of how subjective it is.
Fast Times at Ridgemont High is almost as bad as Animal House.
Some of my favorite comedies: Groundhog's Day, Airplane, Seven Chances, Annie Hall, Love and Death, Duck Soup, A Night at the Opera, Ghostbusters, The Big Lebowski, Hot Fuzz, The General, It Happened One Night, M*A*S*H, Spinal Tap, Kiss Kiss Bang Bang, Rushmore, This Is Spinal Tap. Nothing too out there, mostly pretty mainstream (or at the very least, highly-regarded) American comedies.
EDIT: Also it's been a year since I've seen Animal House, and about 3 since I saw Caddyshack, so I may need to see them again to be completely fair.
