Jesus the Douchebag shirt
Oderus Urungus (singer of GWAR) played the role of "Satan" in the movie called "Jesus, the Total Douchebag." The movie was intentionally made to be as visually flawed as possible (there were air conditioners, sneakers, and other modern items). The reason for that was so that no one would feel threatened by a movie that was so imperfect. It has gained cult status, and now die=hard fans get to wear a t-shirt to show the world their love for the odd form of cinema.
