In Britain, we have Beadle's About and Ant & Dec Undercover, in America, they have this very good programme with the same type of concept, only a bit bigger and braver. Ashton Kutcher and a gang of jokers basically choose a well-known person, celebrity, at random (I guess), find where they are going, and try to fool them into making themselves look an idiot or really cross. The celebrities they have managed to fool, aka get Punk'd, include Christina Aguilera, Pamela Anderson, Pierce Brosnan, Ray Liotta, Denise Richards, Justin Timberlake, Tom Arnold, Billy Boyd, Dominic Monaghan, Brittany Murphy, Kelly Osbourne, Sharon Osbourne, Seth Green, Jessica Simpson, Jack Osbourne, Pink, Britney Spears, Missy Elliott, Tommy Lee, Katie Holmes, Ashanti, Halle Berry, Penélope Cruz, Robert Downey Jr., Rose McGowan, Jaime Pressly, Alicia Silverstone, Beyoncé Knowles, Matthew Perry, Chris Klein, The Rock, Carmen Electra, Tara Reid, Shannon Elizabeth, Kanye West, Salma Hayek, Kirsten Dunst, Joss Stone, Simon Cowell, Randy Jackson, Tony Hawk, Thora Birch, Akon, Adrien Brody, Mischa Barton, Bam Margera, Neve Campbell, Serena and Venus Williams, Kate Beckinsale, Elijah Wood, Hugh Jackman, Brett Ratner, Rihanna and many more. Sometimes you wonder how they got away with doing some of the stunts, as some are bigger than others, but it is hilarious when they do. As far as I know, it was on The 100 Greatest Funny Moments. Very good!
