"Punkin Chunkin" delves into the fascinating world of punkin chunkin, or the tossing of a pumpkin very large distances by use of catapult. Every year since 1986, Sussex County, Delaware has found itself host to Punkin Chunkin World Championships. Will this year be the year the world record for punkin chunkin, 4,438 feet, falls? What does a punkin that's been chunked 4,400 feet or thereabouts look like afterward? Can the insides later be used for pie? Zack Selwyn hosts this sure-to-make-you-want-to-hurl-something special.
