At the 1976 Montreal Olympics, 14-year-old Romanian gymnast Nadia Comaneci performed a routine so flawless that the judges awarded the first perfect 10.0 in Olympic history. There was just one problem: the scoreboard manufacturer had been told before the Games that a perfect 10 was impossible, so they never programmed the board to display it. When her score came through, it read '1.00.' The crowd sat confused for a moment before erupting. Comaneci went on to score six more perfect 10s during those Games. By the end, everyone knew what 1.00 really meant.
