I've wondered how chess might play out with an optional Joker piece. Each side gets one Joker, to substitute in place of one of their Pawns. The Joker can move one square in any direction like the King, but cannot take out any pieces. No other pieces can take out the Joker either, except the opponent's King. Also, the Joker cannot be promoted to any other piece.
The Joker is just there as a silly and annoying distraction to block opponent pieces LOL!
