[ThisIsAnOutrage]

So hard to pick comedies. A lot of great ones have already been mentioned. That said, here are few that have been overlooked:

A Fish called Wanda
The Producers
Dirty, Rotten Scoundrels
Murder by Death
Dead Men don't wear plaid
Scary Movie 2
Undercover Brother
I'm Gonna Git you, Sucka

HM: Beerfest and Me, Myself, and Irene

edit: I see The Producers was already mentioned. Swap in Team America, World Police
