Phineas and Ferb

Phineas And Ferb is an animated series that airs on Disney Channel since 2007. The series follows the antics of two step brothers, Phineas and Ferb, as they try to squeeze the most fun out of the summer days as they can. Each day, Phineas and Ferb come up with an idea for an incredibly massive invention or stunt and spend the rest of the day building the invention or completing the stunt. One day they'd build a roller coaster, another day they'll host a beach party in their backyard, and another day they direct a movie. Meanwhile, Phineas's sister, Candace, tries to bust her brothers by telling their mother about all the ridiculous things they do during the day, however all evidence of the boys' antics disappear before the mom can see, always leaving Candace to look foolish or insane in front of her mother. Another subplot involves the boy's pet platypus, Perry, who is actually a secret agent, Agent P, who each morning is given an assignment to foil the evil plans of Dr. Doofenshmirtz. Dr. Doofenshmirtz is always creating unusual devices and plotting ridiculously stupid evil schemes which almost always inadvertently hide or destroy the boys' invention of the day, thus removing the evidence before the mom can see.
