If you remember the Pittsburgh Steelers of the 1970s, Terry Bradshaw and all, you'll remember "Mean Joe" Greene. Greene played for the Steelers and was part of the "Steel Curtain" defense. He's 66 years old today, but for all of his football fame, Greene may be best remembered for an emotional Coca-Cola TV commercial, where he shows kindness to young fan.

According to Wikipedia:

"Charles Edward Greene, known as “Mean Joe” Greene, (born September 24, 1946) is a former all-pro American football defensive tackle who played for the Pittsburgh Steelers of the NFL. He is considered by many to be one of the greatest defensive linemen ever and was the cornerstone of the legendary “Steel Curtain” defense. He is a member of the Pro Football Hall of Fame and a four-time Super Bowl champion. His nickname, "Mean Joe Greene" stems from his alma mater, the University of North Texas' athletic teams, which are nicknamed the Mean Green."

Here's that Coca-Cola commercial with "Mean Joe" Greene that still tugs at the heartstrings.
