Ellen DeGeneres was left extremely impressed by a toddle r from Liverpool who can name every flag in the world.
The family-of-three were showcasing to America little Harry's incredible photographic memory.
Mum Shellie revealed when he was first born they noticed how big his eyes were.
She said: "We joked that he looked shocked. So, from then, I'd say about 12 months, he started to be able to identify the alphabet, he could spell his name, he could read his name.
"18 months he could identify shapes."
Interviewing Harry, Ellen first asked him how the long plane ride was.
The bright youngster replied: "The plane ride went up and down and round and round and I couldn't believe it."
Ellen then proceeded to test Harry to see whether his knowledge was really that good.
The host held up various photo print outs of flags, Harry accurately named the flags for Australia, Malaysia, the United Kingdom, Cyprus, Russia, Indonesia, St. Vincent and the Grenadines, Cameroon, the Vatican City and Thailand.
An impressed Ellen then asked: "Do you know you're super smart?
"It really is incredible, like what are you going to do?
"You have to keep challenging him, right? What's the new thing that you're challenging him with?"
Steve told Ellen that they were teaching him logos, before disclosing a funny story.
He said: "So, I bought him a logo book of all the corporations globally. And we were going through, and I think we were on the page 300, and we got to the Playboy logo.
"It's bad. So, I looked at it, Ellen, and he said, 'Daddy, what's this?' Shall I just skip the page? But you can't do that with Harry.
"So, I said, 'It's the Playboy logo.' And he goes around telling everybody he loves Playboy."
Ellen then surprised the youngster, holding up a Disneyland logo and revealed they were treating the family to a day at the park.
