Happy Days legend Henry Winkler popped in to the Prime Minister's home this week.
The actor is in town to launch a campaign which aims to boost the confidence of youngsters with special educational needs.
After meeting with Sarah Brown to discuss the project, the 64-year-old spoke of his own battle with dyslexia.
"Every child has greatness inside them. We need to help them to dig it out and give it to the world," he says.
"A society needs every citizen, every child to be at the top of their potential."
Henry has penned a series of children's books about a ten-year-old boy, Hank Zipzer, who has a learning difficulty.
