Jerry Lewis, All Done with MDA

Jerry Lewis is all done with the Muscular Dystrophy Association (MDA).

The legendary comedian has "completed his run as its national chairman," according to a statement released by the Association on Tuesday.

"Jerry Lewis is a world-class humanitarian and we're forever grateful to him for more than half century of generous service to MDA. We will not be replacing him as MDA national chairman, and he will not be appearing on the Telethon," said R. Rodney Howell, MDA Chairman of the Board of Directors.

The news comes just days after Lewis, 85, was seen at the Television Critics Association panel in Hollywood, where he criticized reality television and shot down rumors about his hosting duties at MDA.

Lewis was there to discuss his upcoming documentary, "The Method to the Madness of Jerry Lewis."

"The kids they get on 'American Idol,' they're all McDonalds' wipeouts. ... They all worked there and now they're doing that," Lewis said.

Lewis first became involved with the MDA in 1952. In 1966, he began hosting the annual Labor Day telethon, which has raised more than $2 billion for muscular dystrophy research.

In 2010, the telethon raised over $58 million.

"The Method to the Madness of Jerry Lewis" airs on Encore in the fall.
