An online casino has a piece of Capt. Kirk.

Actor William Shatner has sold his kidney stone for $25,000, with the money going to a housing charity, it was announced Tuesday.

Shatner reached agreement Monday to sell the stone to GoldenPalace.com, based in Los Angeles.

"This takes organ donors to a new height, to a new low, maybe. How much is a piece of me worth?" he said in a telephone interview.

GoldenPalace.com is noted for its collection of oddities, which includes a partially eaten cheese sandwich thought to contain the image of the Virgin Mary.

"This is a bold new addition to our fleet," GoldenPalace.com Chief Executive Officer Richard Rowe said in a statement.

The money will go to Habitat for Humanity, which builds houses for the needy.
