A guy walks into a bar and orders a drink. Other than the bartender there's no one else in the place. Suddenly he hears a voice that says, "Nice suit."
He looks around and doesn't see anyone. The bartender looks busy washing glasses. Soon after, the same voice says, "Nice tie." The guy looks around again, wondering what in the hell.
He finally asks the bartender if he's said something. "No," replies the bartender, "I didn't. Might havebeen the peanuts, though. They're complimentary."
