A man walked into a bar, sat down, and ordered a beer. As he sipped the beer, he heard a voice say, “Nice tie.” Looking around, he saw that the bar was empty except for him and the bartender. A few sips later, another voice said, “Beautiful shirt.” At this, the man calls the bartender over. “Say, I must be losing my mind,” he tells him. “I keep hearing these voices say nice things, and there is not a soul in here but us.” “It’s the peanuts,” explains the bartender, indicating a dish on the bar. “The peanuts?” “That’s right, the peanuts–they’re complimentary.”
