Fox has just greenlit the comedic reality series Smile, You're Under Arrest. According to Variety, the basic premise finds Unaware criminal suspects with outstanding warrants being lured out of hiding with the promise of riches and other rewards, only to discover that they've been duped by law-enforcement officials.

Fox alternative president Mike Darnell stated, "Unlike 'Punk'd,' where things start out bad, this shows starts out being the best day of your life. Everything is fantastic. Then you find out you're under arrest."

Maricopa County, Ariz., sheriff Joe Arpaio, who has gained a reputation of being the toughest sheriff in the States, will be working closely with Fox on the show. Much of the pilot has already been staged, and so far, Fox hasn't had problems getting the alleged criminals to appear on camera. Darnel explains, "Everyone's signed a release. If we say you're going to get $200 if you show up, we give it to you."
