"Big Foot" is an episode of the British comedy television series The Goodies.
Tim and Bill watch "Part 97" of their favourite show The Mysterious World Of Arthur C. Clarke.
A voiceover then informs them that the show has been cancelled due to the non-existence of Arthur C. Clarke.
Graeme is seen by the audience to be hiding a wig and nearly letting slip to the others that he is in fact Arthur C. Clarke, fired by the LWT when his disguise was discovered.
And furthermore the trio fearfully discovered large footpaints that thought to belong to the mysterious Bigfoot, but later that night Bill and Greame surprisingly finds out the footpaints turns out that they were made by Tim's gigantic dodgy foot which was swells up to an enormous size after running around the steep mountains.
