Communicating with only obscenities?
1) The amount of information your drill instructor can convey using only screamed obscenities is truly staggering. It's a wonder I can even pee in a parabolic arc anymore without someone screaming, "That fucking thing is so small, why the fuck do you need to use your hand?"
2) I had a piece of equipment RMA'ed back to the States from somewhere hot and sandy. The only documentation was the spray paint on the side of the crate: "WTF assholes? This POS is NFG"
