Joe Pasquale narrates a special documentary celebrating some of the greatest pranks celebrities have managed to play on each other. Highlights include Ant and Dec setting up Simon Cowell in a classic Saturday Night Takeaway moment he would probably rather forget, and Eurovision winner Cheryl Baker falling victim to one of Noel Edmonds' `Gotcha' tricks. Ben Hanlin talks viewers through an elaborate hoax he pullled on former King of the Jungle Joe Swash, and more practical jokes come courtesy of Freddie Flintoff, Little Mix, and Game of Thrones' pint-sized trickster Maisie Williams.
