Whatever happened to Alex Karras??

Alex Karras was a little before my time when he played football, but by all accounts he was a bad ass on the field. An University of Iowa and Detroit Lions football player, Karras 6'2" 255 pound stature was great for bruising people up on the field. But I remember Karras more for his roles in movies and TV. Shows clips from the movies Porkys and Blazing Saddles which included the talented Karra [link]
