Man: Hey, B.D., before you go, just so I got it, gimme your basic 411. Where'd you see service? B.D.: Iraq. Two tours. Man: Two tours. That's plenty, brother. B.D.: Before that, Gulf War I. Man: First Gulf War, too? You're a horse! B.D.: And before that, Vietnam. Man: Hooyah! Lot of layers to this onion! B.D.: Yeah, you might need a bigger pad.
