We have a plumber here in town that has full color vinyl graphics on their vans. On the drivers door is a picture of a guy sitting on a toilet that is cut off at chest level at the window, so it looks like the driver is sitting on the toilet when you see it from the side.

also, back where I went to college there was a hair salon called "Curl Up and Dye"...that amused me :)
