Personally I don't watch many movies, I watch a lot of TV shows. I would highly suggest "The League" and "Psych" both are funny
Go for Ace Ventura (Pet Detective), Ace Ventura (When Nature Calls) and Liar Liar. All these movies will make you crazy.
A really funny film, while being dramatic at the same time, is an old film from back in 1944 called "Arsenic and Old Lace." Cary Grant and Peter Lorre are two of its stars. The drama keeps you on the edge of your seat because it involves murder (which takes place off-screen). Additionally, the life of the star (Cary Grant) is in imminent danger. This is truly an enjoyable film. I've watched it repeatedly, because it is that funny.
