Happily working my way through Dad's Army -- I'd seen a few episodes sent on tape by a fellow North American British comedy fan -- and enjoying it thoroughly.
Just when I think I've seen the funniest possible episode, I see another that I think is even funnier.
Two recent contenders for the title -- Menace from the Deep and Time on my Hands.
Love to hear other opinions.
Also, I have the "complete collection" but am I right that it doesn't contain Christmas specials?
