The request was prompted by an April episode of NBC's "Celebrity Apprentice" that the group said was demeaning.
In the episode, contestants created a detergent ad called "Jesse James and the Midgets." The contestants, including Joan Rivers, suggested bathing little people in the detergent and hanging them to dry.
Calls to the FCC and "Celebrity Apprentice" host Donald Trump were not immediately answered Sunday. NBC Universal representatives didn't immediately respond to e-mail messages, and the telephone rang unanswered at their Los Angeles office.
