I just discovered this on the Wikipedia entry on Guyball.
Queen Elizabeth's High School, Gainsborough
As of 2nd April 2007, it has been proposed that Guyball be played as a house event between the four school houses. Notices were sent out to the entire school to see how many people were interested. The main people who turned up for the first briefing were about 50 Year 7's, and a host of Sixth-Form students who were mostly fans of Green Wing. It is currently being decided amongst staff as whether to go ahead with the competition, as it would add a bit more character to the more in-line syllabus. Mathematics teacher Nigel Bowler is a fan of the show, and is set to see Guyball into the future.
