The creators of Phineas and Ferb wanted to create a fun crossover, and in turn, they maybe accidentally, created one of the best modern Star Wars movies. The best Phineas and Ferb episodes are some of the most well written pieces of television in recent memory. Yet, somehow, the Star Wars cross over takes that formula and manages to make it work perfectly within the context of a new universe. Phineas and Ferb was a risk for Disney, and these two episides pushed that risk even further, and it turned out to be well worth it.
