A drunk is verbally harassing a lesbian sitting at a bar. Before the bartender can intervene, the increasingly annoyed woman zings the intoxicated homophobe with a question.
What do I need a man for? Name one thing a man can do that my vibrator cant?
The bartender laughs, as the drunken man looks perplexed, when suddenly the drunks face lights up.
OK, lets see your vibrator buy the next round of drinks!
