 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 ("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.
 Sometimes, other villains scoff at his level of evil.

 This usually leaves Candace very frustrated.
