Plopping himself onto a bar stool, a man ordered a beer. As he sat there drinking it, he heard someone say to him, "Nice shirt."
He looked around. There was no one else in the place so he continued sipping. Then he heard someone say, "Nice tie." Again he sees no one except the bartender. "Hey," the man said, "you talking to me?"
"Nope," the bartender replied, "it wasn't me. It must have been the peanuts. They're complimentary."
