Pee Wee's Big Adventure, Wayne's World. For some reason these two movies slay me. I laugh to the point of being clinical. Also, an old 'made for TV' farce named 'Evil Roy Slade' has got to be one of the funniest American movies ever made. Been years since I've seen it. Ok, but the secret one I liked was 'The Wedding Planner'...there, I said it...so, sue me.
