Well, for me, it's gotta be Family Guy, I love that show.
After that it would be most of those oldschool 90's cartoons, and even some of the newer ones aswell, 4am here in brazil is when cartoon network gets good, nickelodeon aswell, Rocko's Modern life, Hey Arnold, Cat Dog, Courage the cowardly dog, Cow And Chicken, then the newer ones would be Chowder (that shit is funny as hell) that foster home one with imaginary friends (i dunno the name) oh how could I forget Ren & Stimpy!!
Hmmmmmm, Spongebob can be pretty funny.
Movies: Well anything of Will Ferrel's, Old School, Wedding Crashers, Anchorman, The Legend of Ricky Bobby, newer Will Ferrell stuff isnt all that good though unfortunately, ofcourse there are other things but these ones are all up there.
Hmmmmmm one I remembered now, Little Brittain! That is a great show, the movie Robin Hood: Men in Tights is fucking hilarious aswell.
As many have said aswell, Trailer Park boys is good, Reno 911, Curb Your Enthusiasm, Super Troopers is a fucking funny movie. Oh shit, I dunno the list goes on and on. Hahaha.
