Despite the error, the Chasers managed to defeat contestant Alex who didn’t win the prize money.
Elsewhere, Paul addressed accusations that he gave fellow Chaser Jenny a “dirty look” on the new show Beat The Chasers.
It comes after The Sinnerman gave a look towards The Vixen after she got a question wrong.
Taking to Twitter, the star explained the look wasn’t malicious, it was pure frustration with himself for not getting the answer right.
“I did not give @jenlion a dirty look,” he explained. “I didn’t know the answer. And Jenny takes a lot of hits by buzzing in with pop culture guesses when the rest of us are clueless.”
Paul added: “My annoyance was with me for not knowing the answer.”
Beat The Chasers airs tonight on ITV at 9pm.
