The Korean guy I remember most from M*A*S*H was the big bald-headed guy with the mustache and smarmy smile -- he's the one, for instance, who carves the head of Potter for his birthday. He turned up in around half a dozen eps, usually as a peddler or huckster of some stripe. He's also the one who tries to sell Potter land for the new compound when they are about to "bug out." I don't know his name, but he's a funny dude.
