I watched the episode "Man In The Blue Suit", there is one Kramden apartment scene where Trixie talks about how much money Ed lost playing poker the night before. She said: "If you go by the pawn shop downstairs and if you see four bowling balls instead of three, don't be surprised. The fourth one is Ed's."

I don't think a brownstone apartment building would be big enough to have a pawn shop. Perhaps Joyce meant to say: 'If you go by the pawn shop outside..."???
