Most expensive kidney stone
William Shatner
25000 US dollar(s)
United States ()

On 18 January 2006, it was announced that Star Trek actor William Shatner (USA) had sold a kidney stone that he had passed the previous year for $25,000 (then £12,700) to online casino Shatner donated the money from the sale to the Habitat for Humanity housing charity.

The casino originally offered just $15,000 (£7,600) for the stone, but Shatner insisted it was worth more, adding that his Star Trek tunics have sold for over $100,000 (£50,800). The stone will join the online casino's growing collection of curiousities, which includes a potato in the shape of The Who guitarist Pete Townsend (UK), and a toasted sandwich bearing an uncanny likeness of the Virgin Mary.
