Dave Allen was an Irish comedian popular in the UK from the 1960s until his death in 2005. His reputation is as a cantankerous irreligious fellow, but this family-friendly moment is widely held to be his best sketch. Someone on YouTube thinks it's the best British TV comedy sketch of the 1970s. There's some pretty stiff competition on that front, if you ask me. (Mastermind, from The Two Ronnies, is the best British comedy sketch of the 1980s. Dead Parrot was 1969.)
