Peter in Auckland, New Zealand sent this one in. He writes,
Is there anything more useless to the modern man than an old pocket watch? I mean, who wants to be constantly reaching into his pocket to check the time on something that doesn’t make phone calls or play Angry Birds? I would posit, however, that yes, there are many things more useless than an old pocket watch, among them broken chairs and 1 foot-long scraps of flooring mouldering under your house… but more on those later.
