Penguins fans cheer Lemieux in attendance for Game 5

Mario Lemieux always showed up for the Pittsburgh Penguins big games during his playing days, so why would Monday night be any different?

The Hockey Hall of Fame forward showed up for Game 5 of the Eastern Conference First Round against the Philadelphia Flyers at PPG Paints Arena.

Lemieux played all 17 of his stellar NHL seasons in the Steel City, leading the team to two Stanley Cup championships. 

Understandably, Penguins fans were happy to see him when he was shown on the scoreboard.

No. 66 gave a wave and a thumbs up to the adoring fans.

The one they call Super Mario was inducted into the Hockey Hall immediately upon his retirement in 1997 with the mandatory three-year waiting period waved. His career included two Conn Smythe trophies, three Hart trophies for most valuable player, six Art Ross trophies as the League's top scorer and the 1985 Calder given to the best rookie following his 100-point first season.

Only six other rookies have scored 100 points in their debut season, including Lemieux's former teammate and current Penguins captain Sidney Crosby.
