I was actually behind an Escalade with that license plate the other day! About 10% of my brain was offended, but the other 90% gave way to laughter. It was just so cartoonish - it raised "piss on" decals to the level of a quip from Mark Twain! Who but a cartoon villain actually goes around praising sin?
A second's reflection told me that he wasn't praising "sin" like the Nazi's extermination of six million Jews though. No, he was celebrating the "naughty," fun things we do - like getting blitzed and hooking up with a hot stranger for the night. 'Cause dude, that ROCKS! Ooh, but what if another dude got blitzed and hooked up with your little sister for the night? Would that rock? If you're human at all, I hope you'll say "no." But then...it'd be a total bummer if you had to rethink a vanity plate that rox as hard as yours.
