“I’d love to say it’s just a number, but it’s a bl**dy big number,” he admitted.
The presenter went on: “I’ve only mentally got past writing Richard Hammond, Form 5B! But Jeremy Clarkson is coming up to 60, which is a bigger number than 50.”
Richard’s new chat comes as he prepares for the launch of his new programme, Big, which looks at the world’s largest structures.
He will explore the biggest car factory in Germany in the first episode, followed by the Super Galaxy plane and Austria’s Kölnbrein Dam.
Big airs tomorrow at 9pm on Discovery.
