A guy sits alone at a bar, drinking his beer. From out of nowhere, he hears a voice say, "You look great, man! Have you lost weight?" He looks around, and confirms that the only other person in the bar is the bartender, who is all the way at the other end of the bar. He shrugs it off, and takes another drink of his beer.
"That's a really nice suit. It looks good on you," the voice says again.
The guy looks around, and before he can say anything, the voice says, "You have very nice eyes."
The guy freaks out, and shouts, "Hey, bartender! Come here!"
As the bartender arrives, the voice speaks again. "That's a nice haircut!"
"Who keeps talking to me?!" The guy asks the bartender.
"Oh, that?" The bartender says, "It's the peanuts. They're complimentary."
