Chose Father Ted even though i didn't know it was British, it was without a doubt one of the best things on tv ever. Blackadder would be my second choice, some of the lines in that were pure brill, completely random. Here's a good quote from Father Ted anyways.
Mrs Doyle: What would you say to a cup father?
[offers him a cup of tea]
Father Jack Hackett: FECK OFF, CUP!
