When I was in high school and Boy Scouts, we had a Vietnamese boat person refugee, and his name was pronounce "Yahm", but it was spelled Dung....you can imagine how this went over in a redneck Texas town....

ANyway, the guy was smart as Hell, blew all us crackas out of the water, but he was super serious and wound real tight. In Boy Scouts he treated it like Green Berets or something, trying to teach us extreme survival shit and yelling like he was gonna stroke out if you didn't get it the first time....he must have lived through some intense shit, though....
