A good looking middle-aged woman walks into a bar to get a drink after a long day at work. she walks to the bar and sits at the bar. after a few seconds of pondering, she raises her arm to order a drink.
when she does, the other patrons notice she doesn't shave her pits. she raises her arm again when she's finished to order another drink.
after she finishes, an older man on the other side of the counter calls the bartender over. He tells him "give that good-looking ballerina over there a drink on me." the bartender asks, "how do you know she's a ballerina?" the man answers, "of course she's a ballerina, son. Any lass who can raise her leg that high has to be a ballerina."
