Lady standing at bar

[Apnababa]

There was this lady standing at a bar and she kept raising her hand to get a drink.
However when she raised her hand a massive amount of armpit hair would show because she didn't shave for years.
Finally after about nine times, the drunk at the end of the bar said to the bartender: "I want to buy that gymnast a drink."
The bartender said "How do you know she is a gymnast?"
And the drunk says "Anyone who can raise her leg that high has got to be a gymnast."
