Gordon Ramsey 's Bank Balance returned on Wednesday night with players Ruben and John, who were cousins and lived together.
But the duo infuriated viewers as they failed to correctly answer several questions, including admitting they did not know a single Blue Peter presenter.
On another question, one of the players was convinced a giraffe was one of the "big five" animals, though his counterpart was not sure, but he went ahead and guessed it - but the answer was wrong.
In a different question, the men were quizzed on who had played Doctor Who, with one immediately guessing the incorrect answer "Benedict Cumberbatch".
Astoundingly, one of them even guessed Matt Baker, who did not play Doctor Who - but would have scored them a point in the Blue Peter question.
When asked to name four novels by Charles Dickens, one of the men confidently answered "Moby Dick" - and it was wrong.
Pained, Gordon exclaimed: "No! Not by Dickens!"
"Oh God, we look so thick," said Tom.
Ruben replied: "Yeah, 100%, that's fine though."
Gordon then joked: "Moby Dick or a pair of d**ks?" But Tom and Ruben managed to leave with £16,000 anyway.
Viewers were also tearing their hair out as the players had to stack the blocks they had earned on a balancing board, and if it failed to balance they would lose their winnings.
But Tom and Ruben had a novel way of balancing their blocks, unevenly rather than stacked neatly together, which made viewers incredibly anxious, with many criticising their methods.
One tweeted: "This is actually infuriating to watch! Why is Tom blaming Ruben for EVERYTHING when he’s making the mistakes himself?! # BankBalance ".
"I’ve never seen two people on a quiz show and wanted to bash their heads together, as much as Reuben and Tom. There are no words # bankbalance ," added another.
A third remarked: "I can’t believe these clowns didn’t know ANY doctor who actors # BankBalance ".
"They couldn't name anyone who played Dr Who. A Single Blue Peter presenter. More than 1 Charles Dickens book, and yet they walk away with 16k. Sign me up. # BankBalance ," added a fourth.
