Apparently Britney drove over a TMZ reporter's sock? And so (because what else was he going to do with it) he's put it up on Ebay.

"AUTHENTIC SOCK ACTUALLY RUN OVER BY BRITNEY SPEARS. IT WAS WORN BY A TMZ CAMERAMAN ON THURSDAY WHEN BRIT DROVE OVER HIS FOOT. TIRE TREAD GUARANTEED AUTHENTIC! TMZ WILL DONATE ALL PROCEEDS FROM THIS SALE TO THE CHILDREN'S DEFENSE FUND."

I suppose at least it is going for a good cause?
