There is no show quite like Disney Channel's Phineas and Ferb. From its premiere, the show established itself as being in its own league. Phineas and Ferb are step-brothers whose only goal is to make all one-hundred and four days of summer vacation the best they can be.
From building rollercoasters to going to space, the boys and their friends Isabella, Buford, and Baljeet took every day as a new challenge making the most of every hour. Their older sister, Candace, took the opposite approach, spending her vacation trying to bust her brothers for their inventions. All the while, Phineas and Ferb's pet platypus, Perry, secretly worked as an agent for O.W.C.A, the Organization Without a Cool Acronym, thwarting evil scientist, Dr. Heinz Doofenshmirtz.
According to IMDb, these are the show's best episodes.
