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."
