Marine

An airman in a bar leans over to the guy next to him and says, "Wanna hear a marine joke?" The guy next to him replies, "Well, before you tell that joke, you should know something. I'm 6' tall, 200 lbs, and I'm a marine. The guy sitting next to me is 6'2" tall, weighs 225, and he's a marine. The fella next to him is 6'5" tall, weighs 250, and he's also a marine. Now, you still wanna tell that joke?" The Airman says, "Nah, I don't want to have to explain it three times."
