Last night's episode of ITV's Saturday Night Takeaway saw the screening of a prank which Ant and Dec pulled on host of 'The Chase', Bradley Walsh.
Walsh had been pranked by the pair 15 years ago and swore never to be caught out again.
Ant and Dec took over an entire episode of the popular quiz show. There were hidden cameras. The entire crew and the chaser were in on it, as were the four contestants, who were actually actors.
One actor told Walsh that he'd also applied to appear on BBC's Pointless, as "it's more intellectual". They also ensured the filming as interrupted by a rubbish truck, typos in questions and chaser Jenny getting contestants names wrong.
With answers being fed to the contestants via earpieces, the four ended up playing for an unprecedented £200,000.
