Betty White is doing her part to gray up NBC’s rainbow-hued peacock. The network announced today that it has picked up Betty White’s Off Their Rockers, a hidden-camera show that “follows a band of seven senior citizens who make it their mission to play pranks on unsuspecting younger people.†The 89-year-old White will host the series, which is based on a Belgian show with the much-worse-yet-better name Benidorm Bastards. (At least it makes a little more grammatical sense than our version.)
