reminds me of junior high off season athletics, we all had to do exercises while laid out all over the basketball court, one of the exercises was called 6 inches and while lying on your back, you had to keep your feet 6 inches off the floor and if you got caught letting your feet hit the floor, you had to go to the tip off line and get "licks" from a paddle they had other kids make in shop class (does that exist anymore?).
The demented fuckers who made the paddles would drill holes in the flat spot to make them more aerodynamic I guess. It was painful as hell and hilarious in retrospect the coaches were allowed to do this without any repercussions. The funny thing is it neither scarred me or deterred my behavior
at least they let us keep our shorts on so we didnt have to take them bare ass (not that the thin fabric of our shorts did more than reduce the humiliation )
