American Shaolin (King of the Kickboxers II) (1991)

After being humiliated in the ring by a dirty kickboxer who pulled down his shorts and then hit him, a martial arts master decides to travel to China and enter a monastery where he may learn the Shaolin form of fighting. The film then veers into "Karate Kid" territory where the novice humiliates himself at every turn, is tolerated as a foreigner, and still comes out a champion. The monastery teaches non-violence, but everyone knows that sooner or later the student will catch up with the bad guy.
