Before they even spoke to Carol today, the hosts of the show were already getting into mischief as they sat behind old school desks.
Winding up his co-star, Phillip grated his nails against a blackboard, which left Holly very unsettled.
“That bothers everyone. I don’t like writing in chalk either,” she declared as her co-host continued to irritate her.
“I’m at school, I’m supposed to do stuff like that,” he remarked as his fellow presenter became more and more uncomfortable.
It was all in jest as the pair then regained their composure to speak with the former Countdown star.
This Morning airs weekdays at 10am on ITV.
