While I imagine there must be somebody out there who "tinks" this joke is funny, all I'm thinking is: There must have been something seriously wrong with your DI. To propose such a thing in active, on-the-line warfare. You don't get survivors -- let alone heroes -- by "emasculating" them immediately before putting them in harm's way.
Jokes are funny -- but only in proper context.
If America has ever done this before, I hope we've figured out by now that we need to STOP doing that....
Still, I think we can (and ought) to list this "joke" on our "Descartes Joke List du Jour"....
Thanks for writing, dude.
Sitting down to pee is pretty universal in basic training in the later half of the 2th century. It is a barricks rule, and it exists because we have to clean the latrine spotlessly, continuously. There is usually also a one-showerhead rule. It does not apply to battlefield conditions, and if I were to pick through the things that made me feel emasculated in basic training, this would be a far cry from heading the list.
