I’ve got a black joker card in my wallet. I was walking to the tram stop with someone once, when I saw this playing card face-down on the floor, so I said “bet you I can guess this card,” I knelt down, and I said “I think it’s a joker.” I was about to turn it over when my friend said “hold on, black or red?” I said black and turned it over, and now it lives in my wallet.
