Jerry Lewis dropped an anti-gay slur during the 18th hour of his annual Labor Day Telethon.
The 81-year-old showman used the same word that got Isaiah Washington of "Grey's Anatomy" in trouble.
Prowling about the stage during the live telecast Monday in Las Vegas, Lewis was goofing around and dodging his cameraman, then went into a ramble about imaginary family members.
He mentioned Bart, the older son, and Jesse, who he called an illiterate f-----.
He said, 'No,' and stopped himself before continuing.
Monday's monologue prompted a critical statement today from the Gay & Lesbian Alliance Against Defamation.
President Neil Giuliano called Lewis' use of the term "simply unacceptable."
Giuliano said it "feeds a climate of hatred and intolerance that contributes to putting our community in harm's way."
A spokeswoman for Lewis referred calls to the Lewis' office at Jerry Lewis Films, based in Las Vegas.
A publicist at the office did not immediately respond Tuesday to a phone message by The Associated Press.
Lewis' telethon, in its 42nd year, set a new record by raising $63.7 million to benefit the Muscular Dystrophy Association, topping last year's event by $3 million.
