Phineas and Ferb

Phineas and Ferb is a 2007 animated show produced by Disney Channel. It follows the title characters: Phineas Flynn and his English stepbrother Ferb Fletcher on summer vacation. Every day, the boys embark on some grand new project, 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 Perry the Platypus working as a spy under the name "Agent P" to defeat the latest scheme of Dr. Heinz Doofenshmirtz, a mad scientist driven largely by a need to assert his evilness.
