Dexter's Laboratory
Debuting in 2005, this show follows child genius Dexter and his adventures in his lab. His older sister, Deedee doesn't share his smarts but loves to play around with his snazzy new inventions, which he whips up easily every day. His nemesis, Mandark, is another child genius at his school, Huber Elementary. And of course, Mom and Dad have no clue what's going on behind closed doors.
