This 1959 silent(ish) comedy last for just over 10 minutes and is packed full of brilliant visual gags, from a musician playing at the top of a hill with using a telescope to read his music at the bottom, to someone listing to a vinyl record by holding a needle to it and running around and around.
The short is directed by Dick Lester and it was this that reportedly inspired The Beatles to hire him to direct their films Help! and A Hard Day's Night.
Conceived by Peter Sellers, it also features Spike Milligan and Graham Stark alongside such comedy luminaries as Dick Bentley of Take It From Here fame, Johnny Vyvyan, David Lodge, and Norman Rossington.
This rather poor quality clip is the only trace I can find of it on YouTube, but you can see the full film on Archive.org.
