The reason? Well, Piers is sick and tired of the hype surrounding the movie franchise, apparently.
He ranted: “I don’t get it, I don’t like it. I have never watched it, I would never watch it.”
However, Richard wasn’t having ANY of it, and as Piers walked in front of him, he whacked him round the head.
The pair’s co-host Susanna Reid could be heard squealing in the background before the camera panned to a very chuffed looking Richard.
Piers then told him: “You’re on the brink of brink of being fired for attacking a co-worker in the workplace.”
Richard quipped back: “You didn’t feel a thing through that weave!”
Susanna then revealed: “During the interview the floor manager came onto set to give piers his medication.”
Hamming up his pain, Piers added: “I need medication to get through this show, trust me. I think I have post traumatic stress disorder.
“I’m actually feeling pain and a certain amount of stress.”
We feel your pain, Piers. Usually every weekday morning.
