Ninja Bachelor Party

Ninja Bachelor Party is a 1991 lowbudget comedy film produced by and starring Bill Hicks, Kevin Booth, and David Johndrow. It is a parody of martial arts movies and was intentionally dubbed improperly. It was filmed throughout Austin, Texas, and Houston, Texas, over the course of ten years due to the producers not taking the project seriously.

That night, Clarence experiences a dream in which an old martial arts master from Korea tells him to fly to Korea and train. The next morning, Clarence departs for the airport, flies to Korea, and meets the old master that he saw in his dream the previous night. The master trains Clarence with sparring and meditation.After finishing the training, Clarence returns to Shotsis apartment in America to challenge Dr. Death to a fight that takes the two throughout the city and back to the apartment. Upon returning, Dr. Death holds Shotsi at knifepoint. After channeling the master for help, Clarence receives a bike, which he uses to ride into Dr. Death, splitting him in half and killing him. After he wins, Shotsi leaps into Clarences arms and the master appears right before him, revealing that he and Dr. Death were the same person all along, and telling him that he has to do one more thing before becoming a ninja warrior. The master tells Clarence that he did the right thing after he literally dumps Shotsi. ........
