Two Bumper Stickers in my parking lot at work. Next week I change offices and won't get to see them anymore...
"WWBD" (picture of hounds-tooth hat in background)
What-Would-Bear-Do? Paul "Bear" Bryant has finally ascended to the right hand of God the Father Almighty!
"God Did It" (airbrushed sunrise in background)
I can't help supplying the rest of the sentence: "... and He Has to Clean it Up!"
