There was a bumper sticker that was moderately popular here in the Texas notch of the bible belt back in the 70's. It said, "WARNING: in case of Rapture, this vehicle will be unmanned."
When I first saw it, in my naivete--honestly, I swear--I thought it was a redneck sexual reference and meant that if the driver's girlfriend was giving him a blowjob, he wouldn't be paying attention to his driving and might be weaving all over the road.
"Can you believe there are still people suckering for this shit? Hehehe!"
