This sketch involves John Cleese as the Minister of Silly Walks being presented with a "walk in progress" by one Mr. Pudney (Michael Palin)— which turns out to be actually not that silly.
There's a brief appearance by Mrs. Twolumps (Carol Cleveland in the Hollywood Bowl version), and for some reason (possibly to display the full range of the minister's silly walks) Terry Jones as a shopkeeper near the beginning of the sketch (not in the Live version).
