A guy walks into a bar after a long day at work and orders a drink. As he sits there, mulling over his day, he hears a high-pitched voice say, “That shirt looks great on you!”

The man looks around, doesn’t see anything, and returns to his drink thinking nothing more of it. But then, a moment later, the voice returns, this time offering, “You seem like a really cool guy!”

Again, the man looks around, sees nothing, and returns to his drink, wondering if he should get checked out by a professional. Finally, when his nerves have cooled and he believes the voice is gone, he hears, “I bet your parents are really proud of you!”

He slams down his drink and looks around wildly. Frustrated and finding no possible source of the voice, he calls over the bartender. He says, “Hey barkeep! What’s that voice I keep hearing?”

“Oh, those are the peanuts,” the bartender replies. “They’re complimentary.”
