Phineas and Ferb is an American animated musical comedy television series produced by Walt Disney Television Animation. Originally broadcast as a one-episode preview on August 17, 2007 and again previewed on September 28, 2007, the series officially premiered on February 1, 2008 on Disney Channel, running until June 12, 2015. The program follows Phineas Flynn and his stepbrother Ferb Fletcher on summer vacation. Every day, the boys embark on some grand new project; these are usually unrealistic given the protagonists’ ages (and are sometimes downright physically impossible), which annoys their controlling sister, Candace, who frequently tries to reveal their shenanigans to her and Phineas’ mother, Linda Flynn-Fletcher, and less frequently to Ferb’s father, Lawrence Fletcher. The series follows a standard plot system: running gags occur every episode, and the b-plot almost always features Phineas and Ferb’s pet platypus Perry the Platypus working as a spy (named “Agent P”) for OWCA (the Organization Without a Cool Acronym), to defeat the latest scheme of Dr. Heinz Doofenshmirtz, a mad scientist driven largely by a need to assert his evilness (although he is not especially evil and has a good heart in some situations. ) The two plots intersect at the end to erase all traces of the boys’ project just before Candace can show it to their mother. This usually leaves Candace very frustrated.
