I watched a couple of episodes of Porridge the other night, although I can't remember which channel it was on. Open All Hours was always a favourite of mine, but it's not the same without Ronnie Barker and the re-hashed modern version sadly doesn't have the same appeal.
I'm not sure if this has been mentioned yet, but I used to enjoy watching The Adventure Game on BBC2 (when I had the chance - we were a one-telly family in those days).
Was that the one with the talking rubber plant on a hostess trolley ?
