A man walked into a bar and sat down, ordered a beer and drank it until suddenly he heard a voice.

Voice: Nice tie.

The man looked around. Nobody was there except him and the bartender.

Voice: Really cool shirt, too.

The man was concerned. He thought he must be losing his mind.

Voice: I like your hair like that!

Finally concerned, the man said to the bartender, "I keep hearing this voice."

The bartender replied, “Those are the peanuts, sir. They're complimentary.”
