Martial Arts Movie Question? Plz Help?!

There was this movie I saw as a kid, about an American who really wants to be a shaolin monk!. They won't let him in, so he sits on a rock outside the temple for days and days, rain and all!. Finally they let him in, and they shave his head bald!. He teaches the monks to have a little fun, while they're cleaning these big rice dishes I believe, he teaches them the song "Summertime blues"!. Towards the end of the movie he has to go through this crazy obstacle course, in which stuff hits him in the stomach and cause him to bleed!.

I don't remember the name of the movie! It's probably an 80s, early 90's movie!. Its a comedy/action/martial arts movie!. Please help!. Thanks!.Www@Enter-QA@Com
