In the early 1980s, before the Jerky Boys brought prank phone calls to a mainstream audience, a group of Oklahoma teenagers were conducting strange backwoods experiments with their land-line telephone. These underground prank calls gained infamy, and became known as Park Grubbs, garnering such fans as The Flaming Lips, Daniel Clowes (Ghostworld, Art School Confidential), and Peter Bagge (Hate). Directed by two Okie filmmakers, Bradley Beesley and Ben Steinbauer, and featuring interviews with both the pranksters and the pranked, the legendary Park Grubbs prank calls come to life in this one-of a-kind documentary.
