While in the USAF in the early 70’s my friend put a small steering wheel on his VW Bug.
I had a Dodge Colt w an adjustable steering wheel, which I dropped to the lowest position.
Steering w my knees, I held the old VW wheel in my hand as I approached the entrance to work and my buddy in the passenger seat.
Having caught the attention of coworkers, I lifted the loose steering wheel with a look of panic and handed it to my buddy, he faked panic for a second and handed it back to me.
Our coworkers scattered from the intersection.
That has to be my best all time prank.
Years ago I saw a little article in a car magazine.
Someone with way too much time on his hands took the body off a car (might have been a ‘61 Chevy), rotated it 180, and bolted it back on the frame. He hooked everything up so it was actually street legal, and started to drive around in it.
It caused panic everywhere it went, and the cops finally told him to get it off the road.
