Hey, I have a hearty dislike for cute and clever shirts as well, I just like these cause they're so offensive they're bound to get a reaction. I used to have this Marilyn Manson shirt that said "I Am the God of Fuck" (which was a Charlie Manson quote, anyway). I wish I still had that one.
But, still, the grand champion and shirt that has gotten more reactions than any other shirt I have, is my Twiztid shirt with the Freek Show cover on it.
