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 sailor says, ''Nah, I don't want to have to explain it three times.''
