I never saw the first one, but this movie is so funny! I'm not 100% sure, but I think this was the first movie with Billy Crystal that I ever saw, and I didn't even see the whole thing when I first saw it! He's so funny in this movie, and there's other funny moments in the film too. I also like the part where Phil (Daniel Stern) calls the radio station shrink telling him about the clothes in his closet, then Mitch (Crystal) grabs the phone from him and says "Kenny has to go. He's cooking breakfast for his underwear", and the shrink says "Who is this?", and Mitch says "This is a pair of his socks.".
