A man went into a tavern after work and ordered a beer.

The bartender placed his beer on the bar alongside a bowl of nuts.

As he started drinking his beer, he heard a female voice saying seductively, "You have nice hair."

The man looked all around him but couldn't see where the voice came from. A minute later he heard the same voice saying, "You are very good looking." The man was really puzzled by this so he asked the barman what was going on.

The bartender replied, "It's the nuts - they're complimentary."
