Aw Nuts

A guy goes into the bar and sits down and orders a drink. Other than the bartender, there's no one else in the place. All of a sudden he hears a voice that says, "Nice suit." He looks around and doesn't see anyone and the bartender looks busy washing some glasses. A little while later the same voice says, "Nice Tie." The guy looks around again and doesn't see anyone. He finally asks the bartender if he just said something."No," replied the bartender, "it wasn't me. It was probably the peanuts though. They're complimentary."
