NEW YORK – Tracy Morgan had just finished apologizing for his anti-gay jokes, and now the comedian is in hot water again.

In his standup act in New York last weekend, Morgan mocked the mentally disabled, according to The New York Times. This has led to a demand for an apology from the "30 Rock" star by a group promoting the rights of the mentally and physically disabled.

Morgan's wisecracks reportedly included a warning not to "mess with women who have retarded kids."

NEW YORK – The late George Carlin's comedy will come alive again this weekend.

Sirius XM Radio Inc. said Monday it will air a special channel devoted to Carlin's comedy this weekend. Carlin died three years ago, on June 22, 2008, at age 71. This year marks the 40th anniversary of the making of his album "FM & AM."

LOS ANGELES – Conan O'Brien compared his career to Charlie Sheen's and Sarah Silverman, not surprisingly, sang a song with a foul refrain. But it was all for a good cause.

Malaria No More said Thursday that the performances at last week's "Hollywood Bites Back" comedy show helped raise $750,000 toward ending malaria in Africa.

LOS ANGELES – A judge says it's too late for a man to contest nearly $200,000 in unpaid child support for a daughter who was likely fathered by comic Sam Kinison before he died in 1992.

Carl La Bove asked a judge to invalidate an agreement with his ex-wife that required him to make the payments.

Recent DNA tests have shown Kinison likely fathered the child born to La Bove's ex-wife.

Superior Court Judge Thomas Trent Lewis told La Bove during a brief hearing Tuesday that he was years late in contesting paternity and trying to nullify at least $188,000 in back child support.

The 52-year-old La Bove, a longtime friend of Kinison, says he won't give up and is fighting to get his life back since the judgment has ruined his credit.
