Quincy Williams was not joking around with his pregame outfit. The New York Jets linebacker showed up to his team's rivalry matchup against the Miami Dolphins on Sunday, December 7, dressed up in a Joker outfit - complete with sinister facepaint portraying the late Heath Ledger's 2008 portrayal of the villain - paying homage to the special "Gotham City Football" uniforms that the team is wearing for the game.
