Confused Revulsion (Night Bazarre, Chiang Mai, Thailand)

How is it that this shirt exists? Its not clever or funny like some of the other shirts in this market: "dumb and dumber" with a picture of Bush Sr. and Double U or the icon of a bunny mounting a duck from behind that just says "Wrong" - rich!.

How is it that this world is so screwed up that a) someone thought this up, b) someone printed this shirt and c) there is obviously a market for it and some asshole actually buys and wears this shirt around? Am I missing the point or some sort of pop culture play here? I just don't get it and there is no way that I can stretch my mind to a point that thinks this is alright. Can someone tell me what is going on here?
