It took Creators Dan Povenmire and Jeff "Swampy" Marsh sixteen years to get this show on television.
Phineas and Ferb is the longest-running Disney animated show, lasting from 2007 to 2015, beating Kim Possible (2002) for five years from 2002 to 2007.
Season Four, Episode Twenty Four, "Phineas and Ferb: Star Wars," had Ferb say the most lines.
The first drawing of Phineas was on a piece of butcher's paper, drawn with crayon in a restaurant.
Director and Creator Dan Povenmire, and Director Zac Moncrief left Family Guy (1999) to work on this show.
