Danny Wallace is a writer and television presenter, who wears glasses and used to have a cat. His first solo book, Join Me, was described as "one of the funniest stories you will ever read" by the Daily Mail. His second book, Yes Man - in which he decided to say "Yes" to everything - is currently in production with Jim Carrey in the lead role. It was described as "hilarious" by more than four national newspapers, and Richard Madeley. Both books were Sunday Times bestsellers.
