I'm going to go against the grain here. Iron Mike has made a career of being scarier, crazier, and more intimidating than anybody else. When his actual boxing skills deserted him (which was a long, long time ago), all he had left was this frightening mystique. What better way to play to his last remaining strength than getting a tattoo on his face, making him look even scarier and crazier than he did before? A face tattoo was probably one of the more prudent career moves ever made by Mike Tyson.

Mike Tyson is the poster boy for bad tattoos.  This should also convince kids that temporary tattoos aren't that bad after all.

I think this one could be expanded to a more generalized "It makes you look like a dumb-ass."

Do I really need to explain how ridiculous this is?
