Why You Play Until the Clock Hits 00:00

This is a popular clip on Youtube of the ending to a basketball game.  Watch as the home team celebrates what they think is a winning shot.  People storm the court to celebrate with the players but they forget that there are still 0.6 seconds left on the clock.  By not even defending they allow the visiting team to get the ball to almost half court and take a shot.

Always Always make sure there is no time left on the clock.  Anything can happen at the end of a game.  Don't celebrate winning too early.
