The Little Britain star is busy working on his first memoir, entitled Camp David, for release later this year, and the 40-year-old is enjoying recalling experiences from throughout his life.

"I did keep diaries from about the age of 30, so I've got a lot of stuff there. I think the hardest thing is recalling people's names - like a teacher who taught you 30 years ago."
