Is There Something In The Water At Mt. Lebanon?

Broadcast.com founder Mark Cuban is one of many celebrities associated with the town of Mt. Lebanon. Ming-Na (most well-known for her appearance on ER), Gillian Jacobs (one of the stars of Community) and Pittsburgh Penguins legend Mario Lemieux are just a few of the names in connection to the Pennsylvania town. Andrew Mason, the founder of Groupon, grew up in Mt. Lebanon. Is this all a coincidence? Or is there something magical about this place that has allowed it to spawn so many successful people?
