The plot of this episode centres on a fad for graffiti featuring the Chad character. As described in the episode, the character is a bald man with a long nose who peers over a wall, which is inscribed with the slogan "Wot - no ____?" Chad graffiti first became popular in Britain during the Second World War, frequently bemoaning wartime shortages in militiary and civilian life.
