I've never really found a good, consistent translation for ドッキリ大成功 - the link to Candid Camera is obvious, as it's pretty much the exact same show, but it always sounds clunky to me in English, and using something like Punk'd never seems to fit the theme most of the time. So if anyone can think of something better, feel free to change it up!

Also there's a mini-pun in the title here, as it's a combination of 大成功 (/daiseikou/ 'great success')and 大作戦 (/daisakusen/ 'grand operation/strategy'); not one that translates easily.
