I don't think that Rodney Dangerfield is funny all the time, but in this comedy he delivers perfectly. He fits perfectly it the role of a rich, successful businessman who starts college to achieve a certificate, which he doesn't have. The way he does this in his own, relaxing and laid back-style is great and really funny. A very cool plot indeed, that's for sure. The movie is full of great fun and has many exciting moments in it, so I suggest that everyone check this out for themselves to experience that. The last scene on the diving board is especially great. Totally hilarious, and I laughed all the way through it.
