These Peanuts Are Very Well Mannered

A man walked into a bar and sat down, 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. 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. "They're complimentary."
