A 1950s BBC radio show which launched the careers of Peter Sellers, Harry Secombe and Spike Milligan. Characterized by an incredible number of silly voices, surreal plot lines, and counterintuitive uses of sound effects.
Only mentioned here because some of sudo(1)'s insults are direct quotations from the show.
Nitpick: It was never "He has fallen in the water!", it was "He's fallen in the water!".
