David Walliams rocked up to the Edinburgh book festival yesterday for an afternoon of book talking, reading and signing chaired by Sarah Brown, wife of former Prime Minister Gordon. Organisers of the event say it was one of the best they had ever seen.

David revealed:

“’I'm obsessed with smells-I want to do the first scratch and sniff version of Mr Stink”, which technically he did last year when creating the Mr Stink scratch ‘n’ sniff musical. Maybe he should enclose a scratch ‘n’ sniff book in the Radio Times to accompany the TV version?

When asked if he enjoys working with Simon Cowell. He joked that the Britain’s Got Talent boss is always late and is ‘a very evil man’ (but fun).

The comedian and author won hearts at the event by signing the cast of a young girl with a broken ankle and there were some great prizes for the best questions. The kids were desperate to get their hands on them and began firing out the questions, including what size shoes do you wear? His answer was size 11, in case you’re wondering. In the end Walliams had the young crowd standing on their chairs jumping up and down waving their arms in the air.

The Guardian’s Jen Bowden‏ raved: “I’ve never seen so many hands up at a kids event” she added that adults were equally excited.

Cheryl Caira of Scottish Woman Magazine said:

“Never before seen such a rocking Main Theatre @edbookfest as a million kids try to ask David Walliams a question…I want to ask one too!”

When asked if he’d ever consider devoting all his time to writing, he said: “Oh no, I’m a dreadful show off, so I would miss the performing more.”

Still, there is one book he has written that he does not want kids to read, his autobiography, which is due out in October and will be called Camp David.

He jokingly told his young audience: “It’s not suitable for you lot. I’ve done an awful lot of bad things.”
