Replace the question mark with a numberMATH PUZZLE: Can you replace the question mark with a number?
A guy goes into a bar and orders a beer. As he takes a sip of his beer, he hears a tiny little voice say: "Nice tie." He looks around but sees no one. He take another sip of his beer and hears: "A nice shirt, too." Again he looks around and sees no one.
He signals the bartender over, and hesitantly explains that he's hearing voices talking to him... "Of course," smiles the bartender. "It's the peanuts -- they're complimentary."
