A guy is sitting at the bar all alone when he hears, "Nice shirt." He takes a sip from his beer, and then hears, "Nice haircut." He calls the bartender over and says, "I thought I was the alone here, and somebody just said 'nice haircut' and 'nice shirt'. "Who the hell's voice am I hearing?" the bartender says, "It must be the peanuts. They're complimentary."
