“What would Jesus do for a Klondike Bar?”
cheers.
I used to have a friend whose bumper sticker read “No smoking unless you are on fire”. Ironically, I smoked as much pot in that car as I did anywhere else in Tucson that year.
On a related note, I recently saw a “Nixon/Bunker in '72!” sticker on an old hippie van by the liquor store. With a picture of Nixon’s face next to a picture of Archie Bunker’s face, chewing a cigar.
Quite some time ago I saw “If you get any closer I’ll flick a booger on your car”

Honk if you love peace and quiet
I brake for tailgaters
Not a “great” bumper sticker, but I did see my first Obama bumper sticker this past weekend.
I gotta admit, “Obama '08” does trip off the tongue effectively.
