Don't be nuts!

A man walks into a bar. It's empty, except for the bartender. He sits down and orders a drink. He hears someone whisper, 'Psst... I like your tie.' The man looks around but doesn't see anyone. 'Psst... that colour looks nice on you.' He asks the bartender, 'Excuse me, but are you speaking to me?' The bartender rolls his eyes and says, 'No, sorry about that. It's the peanuts. They're complimentary.'
