Thought this was a pretty great story, hadn't heard it before either. A user on Reddit translated a post Jaromir Jagr made on his Facebook:

"The story begins 5 years earlier. It's 24th March 1996. A son was born on this day but not everything was the way every parent wishes. Austin was born a couple of months early. Noone knew what would happen so Mario spent 3 days in the hospital with his wife and son. After three days of stress and without sleep, Mr. 66 got the great news - THE SON WILL LIVE AND BE HEALTHY. Mario got so excited that he decided to play a game the same day. We played against St. Louis and won. I don't remember the exact score but I know that Mario scored 5 goals and assisted on two more. No, that's not a typo, he scored 5 goals + 2 assists Trust me, I was there. If you don't, just check youtube.
Life went on and Mario retired a year later. It was March 1997, Mario scored a goal against Philadelphia with two minutes left and most fans considered this the last goal of his career.
Then, for three years, he devoted his time to his family and golf, but also his club the Penguins where he was the owner. He didn't miss a single game, sometimes he visited practices too and with him his (at the time 4 year old) son Austin. He loved hockey too and didn't do anything without a hockey stick in his hands. One day he wandedred into the staff room and started talking to the person sharpening our skates. Austin: 'Hi Steve, what's going on?' Steve: 'Hi, I'm sharpening the skates for our players, we have a game today.' Austin: 'I know, I will be there. And who's the player on the poster (pointing at Mario Lemieux poster)?'. 'That's your father!' said Steve. 'My father played hockey??'. Steve looked at Austin in disbelief and said 'Your father was the best player in the world for a long time!'. 'Oh, I didn't know,' said Austin and left to continue playing with his ball...
I know for a fact that Mario found out about this conversation between Steve and Austin. A MONTH LATER HE ANNOUNCED THAT HE WAS COMING BACK... The first two games were against Toronto and Ottawa. We won both of them and do you know what Mario's total was? Two games - two goals and five assists. After 3 and a half years of leisure. UNBELIEVABLE. This story about little Austin is in my opinion the main reason why Mario returned to the ice. Austin finally saw his father play and Lemieux proved once again that he is the best player of all times."
