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 the bartender. "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.

"Say what?" replied the man in disbelief.

"You heard me," said the bartender. "It's the peanuts... they're complimentary."
