Bottom is a British sitcom television series that originally aired on BBC2 between 1991 and 1995. It was written by and starring comic duo Adrian Edmondson and Rik Mayall as Richie and Eddie, two flatmates who live on the dole in Hammersmith, London. The program ran for three series, and was followed by five stage show tours across the United Kingdom between 1993 and 2003, and a feature film Guest House Paradiso. The show is noted for its chaotic, nihilistic humour and violent comedy slapstick.
In 2008, Bottom came in at number 45 in a poll to determine Britains Best Sitcom by the BBC. The show continues to be shown in the UK on Gold and Dave, and has been dubbed in other languages. In Spain the show is known as La pareja basura which aired on Canal . The theme music was provided by The Bum Notes, a band that once featured Edmondson, and is a cover of Last Night by The Mar-Keys.
Plans were made in 2012 for a BBC spin-off series, Hooligans Island, featuring the Richie and Eddie characters from Bottom. However, that project was cancelled that October prior to production as Edmondson explained that he wished to pursue other interests.
