Former UFC fighter and current porn star Jon Koppenhaver, whose name has been legally changed to War Machine due to a trademark dispute, has now officially surpassed Junie Browning as the most notorious fighter in MMA. On March 13, 2010, War Machine posted an eBay listing for a "28 year old pro athlete piece of liver or kidney" with a starting bid of $50,000 and customer-friendly free shipping! While he didn't actually specify if the organs for sale were his, or perhaps from some other 28 year old athlete stored in his freezer, it would seem offering any organs for sale, even if they're your own, is likely not legal in the United States. This eBay listing (which surely won't last long) could be the cause of yet another War Machine mugshot.
