So Apparently Waterboarding was the coolest thing used by Bullies in FDR's Private School

[MadBadger]

"Franklin, in short, was a trifle unorthodox, and unorthodoxy at Groton could encounter harsh penalties at the hands of the older boys. One of these penalties was the "bootbox" - being shoved forcibly, doubled up, into a small locker, and being left there. Another, also permitted by the faculty, was "pumping" - sixth formers would call out the name of an offender in study period, drag him quailing and shaking to a nearby lavatory, bend him face upward over a trough, and pour basins of water over his face and down his throat until he went through the sensations of drowning"
