DNA's mind reading hit a hurdle in tonight's Britain's Got Talent 2017 final.
DNA are made up of 43-year-old Andrew from London and 29-yer-old Darren from Essex.
They are a double act of mind readers and hoping to win the show tonight.
"We are mind readers, we can steal people's thoughts in seconds, there's no one else in the world doing it," they said back at their audition. "We're the only act in the world doing what we do, so we're the best at what we do."
After getting four yeses at their original try out, this week saw DNA in the live shows where they again stunned with mind reading tricks.
They made it through to tonight's final however their latest performance didn't go quite to plan.
In one part of their act, they tried to read David Walliams' mind and guess what page number of a book he was looking at.
They claimed it was 81, when it was in fact 31, prompting one half of the duo to react: "31? I got very close.... I'm going to change it. I did get 81, excuse me."
The group ended their final performance with a number trick which also underwhelmed.
"From the moment we met you, we've been influencing every decision you've made," DNA said, "We have influenced every decision you have made since the moment we met you and now we end our journey here on Britain's Got Talent, we are DNA."
But Simon Cowell claimed it was far too complicated to follow in the comments from the judges after the performance.
Of course, it's viewers alone that will decide the winner in tonight's show with the champion walking away with £250,000 and a spot on the Royal Variety Performance.
Britain's Got Talent 2017 airs on ITV.
