A guy walks into a bar and notices he's the only one there, apart from the barkeep, who's on the phone. The barkeep signals him that he'll be with him in a minute. The guy nods and bellies up to the bar to wait. Suddenly, he hears a little voice say, "Hey, you're looking pretty sharp today. New suit?"
The guy looks around but can't see anyone else in the place. He hears the voice again. "Seriously...you are looking good, chum. Have you lost weight?"
The guy looks around again and still doesn't see anyone. "Hello?" he asks. "Is someone speaking to me?"
"You bet! I just had to say that I thought you were looking just super!" A bunch of other tiny voices suddenly rose in agreement.
The guy realizes now that these voices are coming from a bowl of beer nuts on the bar in front of him. He stares at them as the barkeep finally hangs up and comes to serve his only customer.
"What'll you have?" asks the barkeep.
"What?... Oh, a pint of ale, I guess", mutters the guy, still staring at the nuts.
He finally looks up at the barkeep drawing his pint. "What's the deal with these nuts?" he asks.
The barkeep brings the guy's pint over and sets it before him. "They're complimentary", he shrugs.
