"The Collapse of the British Railways Sandwich System" is an episode from "The Goon Show," first broadcast on March 8, 1954. The plot begins in the Clapham Junction tea buffet, where a middle-class Englishman courageously asks to be served, only to discover that all the mustard and cress sandwiches have mysteriously disappeared. Captain Seagoon investigates the case and uncovers that Bluebottle, an arch-criminal and master of disguise, has destroyed every mustard and cress place in the world.
