NEW YORK (AP) -- A national autism group is demanding an apology from CBS over a disparaging remark a contestant on the reality show "Big Brother" made about people with the disorder.

John Gilmore, executive director of Autism United, says his group has been trying to speak with CBS executives since the show aired last Tuesday.

On the show, a contestant named Adam, who said he works for an autism foundation, said he would spend his winnings on a hair salon for people with developmental disabilities "so retards can get it together and get their hair done." The Web site for the show describes him as a 29-year-old public relations manager from Del Ray Beach, Fla.

His remark shocked his partner, Sheila, who replied, "Don't call them that."

Adam responded by saying, "Disabled kids. I can call them whatever I want. I work with them all day, OK?"

A call to CBS was not immediately returned.
