Close to post #21, I had one that said "My Weimaraner Is Smarter Than Your Honor Student." It was on the back window of an SUV I had. I don't put stuff on my painted parts.
I got my SUV inspected yesterday and there was an older model Dodge Ram ahead of me with a chrome bumper. Mounted on the chrome bumper were a bunch of bottle openers like you would see on a vending machine. There were all different brands like Coca-cola, Miller, Budweiser etc. I didn't think of taking a picture but I should have - novel!
Back when I had rescue Greyhounds, had one that said,” My Grey can reach the gate in O.8 seconds, can you.” The male was Very territorial of our large fenced in back yard. The females did not seem to care unless there was a treat involved.
Re bumper stickers proclaiming "my" daughter arresting "your" honor student, my niece, a former honor student, many times over during her school years, is a state trooper.
I had a 1986 Ford Escort. Nothing but problems. I had a bumper sticker made that said I'D RATHER CASTRATE MYSELF WITH A BROKEN BEER BOTTLE THAN BUY ANOTHER FORD.
One of mine used to read:
"Remember when Sex was Safe and Diving was Dangerous?"
Picked it plus a few copies up on the Island of Palau when diving there quite a few years ago, Dave_n.
