Danny Wallace is a journalist and TV presenter and for a while he shared a flat with comedian Dave Gorman. Then one day in the late 1990s he made a drunken wager with Gorman, betting him that he couldn't find lots of other Dave Gormans. Gorman rose to the challenge and as a result the acclaimed show Are You Dave Gorman? was born. Wallace later wrote the 2005 book, Yes Man, based on his idea of saying "yes" to everything for six months, which he doggedly carried out. Yes Man was turned into a Hollywood movie starring Jim Carrey.
