An obnoxious drunk in a bar keeps hitting on an a lesbian waiting for her
date. The drunk just won't take no for an answer.

"Tell you what, I'll sleep with you if you can name one thing a man can do
for me that my vibrator can't!" the lesbian smirks.

The obnoxious drunk thinks for a moment. "Okay, let's see your vibrator buy
the next round of drinks!"
