I “went” to private school and one time me and two friends cut through the girls locker room to get to the main gym. Mr. Hayes caught us ( later turned out taught me to shoot skeet & Trap) and said we were going to go through the “windmill” ( he was walking with a cane), and he would backwhip, then forward, and he wanted a fresh butt in every spin, and we would go on until we got it right... luckily, me and my two buddies managed to jump into the windmill just right, one, two, three..MAN did it hurt...but glad we didn’t have to do it again.
Also got the strap at that school
