That's funny!Seen one on the back of a motorhome Back off or I"ll flush!
My favorite of all time I saw many years ago in WV on a (no offense to the rednecks) but it was on a redneck looking blazer, full size, lifted up, over size tires, just looked like a great off road vehicle for the weekends like my brother & I used to do in his redneck truck, basically screaming 'pull me over, you will find an open container'... but the best was the one bumper sticker that said:
Bong Hits For Jesus
I thought that just said 'Yep, pull me over & you will find drugs, alchohol, & probably a loaded firearm.
