From Warner Bros. Animation, Jonny Test was the story of a fearless 11-year-old boy who volunteered his services as "guinea pig" for the inventions, strength-enhancing stimulants and weaponry created by his 13-year-old genius twin sisters Susan and Mary. In each of the two stories per half-hour episode, Johnny would try out such contraptions as a rocket-powered backpack or "superstrength" lollipop, with hilariously exciting results. Accompanying Johnny in his various exploits was Poochie, his genetically engineered pet dog. Johnny Test joined the WB network's Saturday morning cartoon lineup on September 17, 2005. ~ Hal Erickson, Rovi
