A man went into a bar after work and ordered a beer. As he started drinking his beer, he heard a female voise saying seductively, 'You've got 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 a handsome man.' The man was really puzzled by this so he asked the barman what was going on.
The barman replied, 'It's the nuts - they're complimentary.'
