Reminds me of the idiots out in our town a couple years ago. They went to the lumberyard and bought a few pieces of 4" x 8" plywood. Didn't want to bother tieing it down in the truck. So, they leaned the sheets against the cab of the truck, with the other end down in the bed against the tailgate(must have been a short bed truck). Then one of the guys climbs in back, and lays down on the plywood to hold it down. You get the picture

Worked great up until the point they got out of town and the speed limit was 55mph. Wind caught the plywood, and flung it and the idiot redneck out of the truck. He had to be rushed to the hospital for multiple injuries. (Never heard how he did afterwards)
I can just see the aid car guys:
"So, let me get this straight(surpressing laughter). You layed on top of the plywood........."
