Love the blinking!
Anyway - TMS clips included the titles, Rudolph Nureyev and Piggy in the Sauna (certainally not children's TV), a short clip of Piggy with the railway track on her back.
Many of the clips were the set-up lines without the jokes, which was a bit of a problem. Such as "I may be a nurse but a woman first" and that's it. I think the only joke was from Cythia Birdly!
The best bit was probably the Sir Peter Ustinov interview talking about how you would look into the eyes of the puppet and not the manipulator.
I feel I should also point out that this was a UK list.
The Top 3 are all not really children's programs. The Simpsons and the Mupet Show were always written as family shows and Dagermouse is a comedy classic which deserves to be recodnised as as important as Monty Python or the Goodies with the excellent voices of Terry Scott and David Jason.
The list is definately retrospective - compiled by adults looking back and not children of the day.
