Guyball is a fictional game featured in the British sitcom Green Wing. The rules of Guyball are never fully explained, and are designed to be as confusing and as difficult to understand as possible. However, Green Wing fans have attempted to create their own rules and Guyball societies. The first such society was created at King's College London.
The most renowned player is the fictional half- Swiss anaesthetist Dr Guy Secretan. Due to the similarity between his name and that of Guyball, and the fact that Guyball's specialist terminology has a heavy Swiss influence, it seems likely that Guy invented it. He first played Guyball at Whiteleaf ( "whitliff"), a public school he attended for twelve years (1977–90). Guyball is first mentioned in the seventh episode of series one of Green Wing, "Tangled Webs", as Guy prepares for a world championship semi-final, having won his second-round match in five straight clappers. Other noted players include Markus Geissler, "The Big Austrian", who Guy walked over in the first round because he had shin splints.
The idea for Guyball was inspired by real-life obscure sports played solely at particular real English public schools – such as the Eton Wall Game and Winchester College Football. The awkward pronunciation of the sport's name is based on a quirk of various upper class institutions such as Magdalen College (pronounced (/ˈmɔːdlᵻn/ mawd-lin). It was created by Green Wing writer Richard Preddy, and it was later developed by the other writers.
