A man walked into a bar, sat down, and ordered a beer. As he sipped the beer he heard a soothing voice say, "Nice tie." Looking around he noticed that the bar was empty except for himself and the bartender at the end of the bar. A few sips later the voice said, "Beautiful shirt."
At this, the man called the bartender over. "Hey, I must be losing my mind," he told him. "I keep hearing these voices saying nice things, and there's not a soul in here but us."
"It's the peanuts," answered the bartender.
"You heard me. It's the peanuts ... they're complimentary."
