The Truths

Justin Edwards - Coffee

Lucy Porter - Lying

- Scientists at Queen Margaret University College, Edinburgh, have revealed that women are better liars than men. Found by Zoe.

- The supposedly-true story that inspired the film Saturday Night Fever was completely made up. The film was based on an article in New York magazine about a young man called Vincent, who worked in a paint store by day and owned the dance floor by night. In 1994, the article's author Nik Cohn admitted that he had been sent to a Brooklyn club called 2001 Odyssey to report on working class disco subculture, but never entered the building after someone vomited on his leg outside the entrance. Needing material, he made up a story based on his own memories of gang culture in Northern Ireland, where he grew up. He based the character of what would become John Travolta's Tony Manero on a mod he knew from Shepherd's Bush. Found by Tony.
