A man walked in to a bar after a long day at work. As he began to drink his beer， he heard a voice say seductively “You've got great hair！” The man looked around but couldn't see where the voice was coming from， so he went back to his beer.
A minute later， he heard the same soft voice say “You're a handsome man！” The man looked around， but still couldn't see where the voice was coming from.
When he went back to his beer， the voice said again “What a stud you are！” The man was so baffled by this that he asked the bartender what was going on.
The bartender said “Oh， it's the nuts——they're complimentary.”
