A traveling salesman sits drinking in a bar. He hears a soft voice say, "nice tie." He looks up, but doesn't see anyone.
A few seconds later he hears, "nice shirt." Once again he looks around but still can't see anyone.
When he hears, "nice jacket." he calls the barman over and says, "Look, I don't want you to think I'm crazy but I keep hearing voices commenting on my clothing. But every time I look around, there's nobody there.
The barman said, "Oh, that'll be the peanuts, they're complimentary."
