Britain's Got Talent hosts Ant McPartlin and Declan Donnelly became part of the act with incredible results on tonight's show.
A spooky silent act in a white mask took to the stage with a voiceover requesting that they needed a duo to take part in an experiment to show "how we connect as human beings" - and Ant and Dec were chosen for their telly partnership spanning 30 years.
The presenting duo were seated separately as the hooded figure stood between them and they were asked to raise their hand if they felt a touch.
Only Ant was touched but both he and Dec raised their hands.
The pair were then asked to draw anything of their choice on a board without letting the other one see for the final test on the ITV talent show.
Incredibly they both drew the exact same thing, which when turned around showed the year 1989 - the year they started working together.
At first Simon Cowell was left speechless by the act, before saying he had found it 'emotional' to watch.
And fellow judge David Walliams said: "That was the spookiest thing we've ever seen on Britain's Got Talent. Just a perfect act, well done."
"God this guy with Ant and Dec is f*****g mind blowing," tweeted one viewer.
"WTF!!?? I mean what eh and how?? Amazing. Bloody amazing," said another.
"Surely Ant & Dec won't be in on it? It has to be magic!" said a third.
Ant and Dec were then brought back on stage to confirm they knew nothing about the act beforehand.
"We didn't even speak backstage," they confirmed.

And Dec was amazed to learn he hadn't even been touched.
He said: "I felt it."
