What is the funniest bumper sticker you have ever seen? My friend had one that said "MY OTHER CAR IS A PENIS". I'm not sure what that really meant, but man it was great.
My kid can beat up your honor student. Here's my idea for a bumper sticker. REMEMBER: JESUS LOVES YOU Unless you're riding my ass, then you're going straight to hell!
I saw one once that had a Confederate flag in a circle with a line accross it like a no smoking sign. Anyways, next to that it said "You lost. Get over it!" "My kid can beat up your honor student." "According to my calculations the problem doesn't exist."
