I never found his films funny.
The American Masters program airing on PBS recently has reminded me that he's not really a comedian. I know that comedy is highly subjective, and a lot of people will strongly disagree with me, but I don't think his films are all that funny, they're more silly than anything else. I always get the feeling his 'direction' is to tell people to clown around in front of the camera and we'll call it a wrap.
