On The World Around Us, Arthur Jackson (John Cleese) is interviewed about his wish to be a mouse and his activities with fellow people who feel this way, throwing parties where they eat cheese and squeak.
A consultant psychiatrist, Kargol (Graham Chapman) and his assistant, Janet (Carol Cleveland) present findings that 8 percent of the population are mice and admits that he, too, has felt attracted to mice. He states that this is normal. It is then presented that Julius Caesar, Napoleon, and Hilaire Belloc were also mice.
People on the street are then interviewed on how they would react to people who are known to be mice and a film of a mouse party is shown, narrated by Arthur Jackson.
