The shows' creator and executive producer, Ashton Kutcher masterminds the project and directs the devilish pranks.
From behind the scenes, Ashton has a host of henchmen performing his dirty deeds. The marks don't suspect a thing, until it's too late, and they've been Punk'd.
What sets this show apart is that most of the marks are celebrities. Catching a big star with their guard down and putting them in compromising situations is what goes on here. It's just that simple. It's way more fun to play pranks on celebrities.
