"Punch-Drunk Love" was good, but I think it was because Sandler was in a movie that didn't suck, with a director who could do more than just make poo-poo jokes.

There are one or two moments in "Happy Gilmore" and "Billy Madison" that are funny, but it's not worth watching the movies to find the funny.

Which reminds me a bit of those old "where's the beef" commercials. I can imagine the same old woman watching, say, "Big Daddy" and saying "Where's the funny?"
