"Multiply in your head" (ordered the compassionate Dr. Adams) "365,365,365,365,365,365 by 365,365,365,365,365,365." He [ten-year-old Truman Henry Safford] flew around the room like a top, pulled his pantaloons over the tops of his boots, bit his hands, rolled his eyes in their sockets, sometimes smiling and talking, and then seeming to be in agony, until, in not more than one minute, said he, "133,491,850,208,566,925,016,658,299,941,583,225!" An electronic computer might do the job a little faster but it wouldn't be as much fun to watch.
