|Episodes with Jon Pertwee|
Jon Pertwee (1919-96) was a guest on Countdown.
As an actor, he was most famous for playing a renegade time lord in Doctor Who, a feckless naval petty officer in The Navy Lark and a scarecrow in Worzel Gummidge, and as such could never be accused of lacking "range". He also hosted the murder mystery game show, Whodunnit? and provided the voice of SuperTed's sidekick, Spotty.
On his appearance, the conundrum DALEKSNEC was revealed as a homage to him.
Pertwee died of a heart attack on 20 May 1996, just a few months after his sole appearance on Countdown.
