Why do you call her a ballerina?

This nasty, sweaty woman, wearing a sleeveless sundress,
walks into a bar. She raises her right arm, revealing a big hairy armpit as she
points to all the people sitting at the bar and asks, "What man out there
will buy a lady a drink?"

The whole bar goes dead silent, as the patrons try to ignore
her. At the end of the bar, a skinny little drunk slams his hand on the bar and
says, "Bartender, I want to buy that ballerina a drink!"

The bartender pours the drink and the woman chugs it down.
After she’s completed the drink, she turns again to the patrons and points
around at all of them, again revealing her hairy armpit and saying, "What
man out there will buy a lady a drink?"

Once again, the little drunk slaps his hand down on the bar
and says, "Bartender, I’d like to buy the ballerina another drink!"

After serving the lady her second drink, the bartender approaches
the little drunk and states, "It’s your business if you want to buy the
lady a drink, but why do you call her a ballerina?"

The drunk replies, "Sir, in my eyes, any woman who can
lift her leg up that high has got to be a ballerina!"
