Williams posted the link to his eBay auction on Twitter, humorously referencing Arby's original jab at the singer's accessory.

So far, the top bid is $10,500. The auction is open until March 2. Proceeds will benefit One Hand to Another, the charity founded by the musician to help underserved youth.
