After lunch on Tuesday, Jeremy Shockey went to sign some autographs and revealed a very purple left hand, stained with dye after he stuck it inside his glove, not knowing that it had been booby-trapped with the unwashable substance that banks use to mark money.

Unsmiling, the temperamental tight end clearly did not appreciate the gag and vowed revenge. "Dead man walking," he warned.
