Taken from Athlon Sports' 2004 baseball preview. . .

So perturbed was one Yankee fan in August 2003 that he actually put pitcher Jeff Weaver -- not his baseball card, not his jersey, not his used bubble gum (a la Luis Gonzalez), just Jeff Weaver -- up for auction on eBay. He described the ineffective mid-season acquisition as being "in fair-to-good condition, hardly used and showing minor wear" and added that he was "acquired by mistake in an attempt to keep him from wearing red socks. Must sell ASAP. Will take offer from qualified bidder... talent not included (missing talent might be located in Detroit; buyer's responsibility to procure; no guarantees)."

Another former Yankee, Jeff Nelson, once sold bone chips from his elbow on eBay, but apparently selling body parts isn't allowed. And yeah, Luis Gonzalez of the Diamondbacks sold a wad of his chewed gum for something like $10,000. I've also heard of souls, entire California towns and minor league hockey franchises being sold on eBay, too.
