2. Keith Jackson is an award-winning broadcaster for ABC Sports, who covered, primarily, college football. He is famous for his gentle demeanor and his folksy sayings, including but not limited to "Fummmmble! Ooooke-la-homa football!" and "Whoa, Nellie, I mean to tell you he got his bell rung!" Jackson, 70, retired in 1999 after 31 seasons with ABC. Critics have noted the recent decline in the quality of ABC Sports, which had its heyday under Roone Arledge (whose tenure might be deemed the "thrill of victory and the agony of defeat" era).
