One of the more popular Monty Python
The basic concept behind the sketch is that in addition to such governmental organizations as the Ministry of Defense, there is a Ministry of Silly Walks that provides funding to individuals in order to promote the specific silly walking styles of these individuals. The skit features John Cleese with an extremely elaborate silly walk, michael palin as a grant applicant, and a film reel of silly walks from around the globe.
On a rather ominous note, the inspiration for this sketch came from british documentaries on The Great War, specifically those involving shell shock victims. The silly walks are mostly inspired by the involuntary twitches of those that suffered mind shattering trauma in the trenches of Europe.
