Johnny Test is an American-Canadian animated television series produced by Warner Bros. Animation, for the first season, and Cookie Jar, for the remainder of the series. It premiered on Kids' WB, on September 17, 2005, which continued to air the series through its second and third seasons. The rest of the series aired on Cartoon Network, from its debut on January 7, 2008, in the United States and internationally. In Canada, the series airs on Teletoon, premiering September 8, 2006. Young Johnny is gung-ho and full of courage. Johnny's brainiac twin sisters, Susan and Mary, use Johnny as their guinea pig for their outrageous scientific experiments. If they can dream it up, Johnny will do it; as long as his genetically engineered super dog, Dukey, can come along.
