Surprised by Dinosaurs!
The idea is a sublimely simple. Take a couple that's living together, pay one of the them a lot of money to deceive the other (by creating a diversion that keeps the other out of their shared home for a time), then watch the hilarity ensue as CGI monsters from the paleolithic era devour the returning couple!
The show will cross demographic boundaries to beat the band.
Should any TV executives wish to hire me for my brilliant programming genius, please note that I will only consider opportunities that include extensive telecommuning and cheap floozies.
