An old nearly blind marine wanders into an all-girl biker bar

He sits down at the bar, squints through his old eyes, sees a woman at the end of the bar and gives her a wave. She sees the old man, lifts her arm and gives him a big wave back, revealing a very hairy armpit. The old marine says to the bartender “I’ll take a shot of whiskey, and send a shot to the dancer at the end of the bar.” The bartender asks “How do you know she’s a dancer?” The old marine says “Well who the hell else could lift their leg that high?”
