I can see a bunch of MD's buying a car with the patella they sold on line.

Last week, William Shatner sold his kidney stone to the Web site GoldenPalace.com for $25,000. Shatner, who donated the proceeds to charity, convinced his doctors to give him the stone, which was taken out last autumn. Do all patients have the opportunity to keep their excised body parts?

Generally, yes. Many hospitals are willing to return everything from tonsils to kneecaps. After a pathologist examines the removed parts and takes whatever samples are necessary for hospital records, the patients can often walk away with the rest.
