David Walliams, Ice Cube, Olly Murs

David Walliams, Ice Cube and Olly Murs go head-to-head with Chris as they show off their knowledge and try to secure a place in the grand final of TV's most unruly quiz and quip their way to the illustrious top spot on the series leader board. The show's regulars are of course back - Stephen Fry describes works of high culture in a language that 'celebrities might understand... street talk' - and David Hasselhoff invites the guests to answer questions about the weird and wonderful 'Hoff's World'.
