MICHAEL Jackson‘s notorious tighty whities are up for grabs. A pair of size-28 Calvin Klein white briefs once belonging to Wacko Jacko will be auctioned on eBay tomorrow, with a reserve price of $1 million. The unwashed underpants have a sensational past. They were part of the evidence confiscated in 2003 by then-Santa Barbara DA Tom Sneddon, who wanted a DNA sample for his unsuccessful child-molestation case against the washed-up King of Pop. The briefs are part of a stash of Jacko artifacts offered by New Jersey businessman Henry Vacarro, who obtained them in a bankruptcy case. For extra authenticity, the briefs come sealed in an evidence bag and wrapped with police tape. Also being sold are the Gloved One’s handwritten note explaining why he wants an annulment from Lisa Marie Presley and a used half-ounce tube of skin-bleaching cream.
