66 (number)

66 (sixty-six) is the natural number following 65 and preceding 67.





The National Football League retired jersey number 66 for Green Bay Packers linebacker Ray Nitschke. The last Packer to wear number 66 before it was retired in 1983 to honor Nitschke was offensive tackle Larry Pfohl who is better known to pro wrestling fans as Lex Luger.

Also, the number 66 is retired by the Pittsburgh Penguins (National Hockey League) in honor of Mario Lemieux. Although not officially retired by the NHL, no players have worn the number 66 since its retirement in Pittsburgh as a sign of respect for Lemieux, considered by most as one of the best players to ever play the game.
