Compliments at a Bar

A man in a bar is enjoying his drink when he hears a voice say, "You look
great!" He looks around, but there is nobody near him. He hears the voice
again, "No, really, you look just terrific!" Again he looks around.
Nobody! A few minutes pass, and again he hears the voice, "Is that a new
shirt or something...because you look absolutely stunning!" At this point
the man realizes that the voice is coming out of a bowl of nuts on the
bar. "Hey," the man calls to the barkeep, "what's with there nuts?" "Oh,"
the bartender answers, "they're complimentary."
