It's the end of an era: He's been the Muscular Dystrophy Association's national chairman since the early 1950s and the host of its Labor Day telethon since 1966. But as of this year, Jerry Lewis is neither—and he won't even be appearing on this year's telethon. The comedian announced he was giving up hosting duties in May, but said he'd make his final appearance on the Sept. 4 broadcast and would hang on to his duties as chair, reports the AP. But the nonprofit agency yesterday announced that he "will not be appearing" and has "completed his run" as national chair. (More Jerry Lewis stories.)
