This is Bill Russell, one of the greatest basketball players to have ever lived, showing how excited he was by Game 7 of the 2013 NBA Finals last night.
Did we mention that Bill Russell is 79 years old, and has 11 rings? Which means that A.) he is just plain tired and B.) he is so far from impressed, considering he has more rings than anyone else in the history of the NBA, and it is highly unlikely that any other NBA player will ever beat that record.
