Former Mythbusters Kari Byron and Tory Belleci make their much-anticipated return to Discovery and Science Channel as hosts of the annual rite of Thanksgiving week PUNKIN CHUNKIN. Byron and Belleci are veterans of the competition’s high-flying action. This year’s PUNKIN CHUNKIN marks their fourth consecutive year of taking viewers behind and beyond the firing lines to record the enthusiastic antics of competitors. At a new venue this year, PUNKIN CHUNKIN: SUPERCHUNK brings together some of the top teams in the competition to unleash a chunking extravaganza like never before. Teams will vie for the top title by taking on various challenges to chunk everyday objects into a cornfield. TV’s, pianos, and even cars… nothing is safe from this group as the Chunkers meet their greatest challenge to date.
