Network spokeswoman Aileen Budow says the joke was delivered by Jackass comedian Steve-O. She says it'll be omitted from the final edit of the "Roast of Charlie Sheen" airing Sept. 19.
The joke refers to the victims in The Station nightclub fire in West Warwick in 2003 as "nobodies."
Rhode Island comedian David Kane's son Nicholas O'Neill died in the fire. Kane says he was insulted by the joke and asked for it to be pulled from the broadcast.
Sheen was fired from the CBS sitcom "Two and a Half Men" in March after a meltdown during which he claimed to be a "rock star from Mars."
