A friend of mine used to have a bumper sticker that said "I <3 Gay Porn." And right next to it he had another one that said "Jesus is my designated driver."
i would love this but the jerk that parked wrong may have been a victim of circumstance. What if the guy next to him parked like an idiot and in turn this guy had to park like a jerk because if the idiot? now you insulted this guy because he didn't have a choice.

Two wrongs don't make a right and whatnot.
