Jerry Seinfeld will honor fellow comedian Bill Cosby with the Mark Twain Prize for American Humor at the John F. Kennedy Center for the Performing Arts in October. Seinfeld will be joined by Chris Rock and some of Cosby's co-stars from his 1980s sitcom “The Cosby Show,” Phylicia Rashad and Malcolm-Jamal Warner, and others. The center announced the lineup Thursday and said the sold-out event in Washington on Oct. 26 would be broadcast in the US in November. Cosby, 72, already received the Kennedy Center Honors in 1998 and a Presidential Medal of Freedom in 2002. Cosby is the 12th honoree to receive the Twain prize. Past recipients include Steve Martin, Whoopi Goldberg and most recently George Carlin.
