Erik Stolhanske
Erik Stolhanske is an American actor, writer, and producer, and one of the members of the Broken Lizard comedy group. He graduated from Breck School, then Colgate University. At Colgate he was part of the troupe Charred Goosebeak, which included the others of Broken Lizard.
He was born without a fibula, and has had a prosthetic leg his entire life. He has since upgraded to a metal prosthetic, as shown in the Broken Lizard standup special, where the other members of the comedy troupe hit his leg with various items, including a metal baseball bat, a hammer, andlarge pink dildos. Since his movie career started picking up with Super Troopers, he has done talks at various venues about his life growing up without a leg, and how he overcame said adversity. He was captain of his baseball team in grade school. He was also featured in the original P90X workout series plyometrics segment.
