You might expect author Terry Deary's favourite subject at school to have been history, considering he's written almost 200 books on it.
However, the children's author says he found the subject "so boring" at school and that's why he's made it his mission to bring it to life in his books.
Speaking at a World Book Day event at Warwick Castle, he said kids love reading about "foul food and terrible toilets".
It was the 400th anniversary of the death of one of the world's greatest playwrights last year.
It seems that Warwickshire's Shakespeare has continued to inspire modern day authors.
Terry Deary, who was born in Sunderland, says the Stratford-upon-Avon playwright is one of his heroes.
"He's a working class lad who joined the theatre and by acting, learnt what worked on stage and started writing and that's exactly what I did."
The author also told us that discoveries, like finding King Richard III's body in a Leicester car park, can help bring history to life.
"I think things like skeletons are really intriguing, you look at one and you think, what was his life like?"
Terry says he constantly aims to engage children through his books content and illustrations.
Although lots of children still enjoy reading, he says you need to help children realise that books can give them something that social media can't.
As it's World Book Day we couldn't resist asking what Terry's favourite book was when he was a child.
