Mind game is sort of funny. Or perhaps I should say, sort of awesome. As far as movies go, I can't think of a whole lot of comedies.
I can think of a couple comedy series, but they're long and not necessarily that funny. Yakitate Japan is straight up comedy, and I suppose the Kamen no Maid Guy is also, but they're not exactly a laugh a minute. Any other comedies I can think of, like GTO or any schoolgirl animu (Azumanga, Minami-ke, Lucky Shit) are all half comedy half slice of life.
