Four days before Carlin's death, the John F. Kennedy Center for the Performing Arts named him its 2008 Mark Twain Prize for American Humor honoree.[7] He became its first posthumous recipient on November 10, 2008.[8] Comedians honoring him at the ceremony included Jon Stewart, Bill Maher, Lily Tomlin (a past winner of the prize), Lewis Black, Denis Leary, Joan Rivers, and Margaret Cho. Louis C.K. dedicated his stand-up special Chewed Up to Carlin, while Lewis Black dedicated the second season of Root of All Evil to him.[citation needed]
