I am not usually into the Brit humour type of series, and for example actually found the majority of Monty Python skits rather boring in fact. However, I happened across Red Dwarf one lazy summer evening and enjoyed it, surprisingly. Are You Being Served came on immediately afterwards, and although it took a bit to catch on it seemed the writers improved as the series went on. It was well into the second season before I discovered the show was supposed to centre about the 'newest' salesclerk, as he was apparently some manner of famous actor in the UK.
I actually have all seven seasons of Red Dwarf on DVD here, and was actually planning on setting aside an upcoming weekend to watch them again. Somewhat addictive, despite Lister's thick dialect. Give it a try!
