This Morning aired a blunder by host Holly Willoughby on Monday morning, or so viewers were led to believe.
During the show's game It's Behind You, Holly and co-host Phillip Schofield had to guess a number of items and people based on descriptions given to them by fans.
Each correct answer would increase the money each viewer won.
Holly decided at the end of the game that she would tally up how much This Morning had given away in total that day.
She did the calculations, while a little confused, before claiming the total to be £1,200.
But Holly was soon told in her ear that her statement was wrong, with Phillip also correcting her.
He said the right total was £1,300, leaving Holly a little red-faced as she laughed it off.
But viewers were quick to point out this wasn't correct, and Holly was right the entire time.
Taking to Twitter to defend the host, fans did their own calculations and correctly worked out the total was £1,200.
One fan commented: "No she was right it was £1200."
A second agreed: "Holly was right, it’s £1200."
Another added: "It was £1200, whoever told you £1300 in the ear piece is rubbish at maths, £500 + £350 + £350 is £1200 babes well done."
As the show returned from an advert break, Holly had been informed of the mistake and that she wasn't wrong after all.
She took the moment to tell all to viewers watching at home, revealing director Barry was behind the blunder.
She said: "I'm feeling very smug, I'm going to enjoy this moment.
"I said it was 1,200 and then I got told by Barry the director in my ear that I got it wrong."
Phillip, who had also mocked Holly, added: "He said 1,300 so loud and confident and it was wrong.
"Barry... so I followed him down the rabbit hole and look what happened... well done [Holly]."
This Morning airs weekdays at 10am on ITV.
