Phineas and Ferb

Phineas and Ferb, an animated comedy series, follows the adventures of Phineas Flynn and his English stepbrother, Ferb Fletcher, on their summer vacation. Each day, the boys and their friends take on some ambitious new project, sometimes to help someone in need, but often just to create something fun. This annoys the boys' sister, Candace, who constantly attempts to get them in trouble by revealing their actions to Mom. Meanwhile, across town, the wannabe-evil scientist Dr. Doofenshmirtz continually attempts to take over the Tri-State area with his various inator devices, and Perry the Platypus, the boys' pet and a secret agent, consistently foils his plans on behalf of the O.W.C.A and his commanding officer, Major Mongram. At the end of each episode, the two plots intersect to erase all traces of the boys' project just before Candace can successfully show it to Mom.
