Simon Pegg, Jon Stewart, and Jay Leno Coming to Phineas and Ferb

If you think that Phineas and Ferb have had some pretty awesome vacations in the past, just wait until you see what they have in store for this summer. The Disney XD favorites have several new episodes coming, with a slew of special guest stars planned.

The summer spectacular will kick off on June 9, with the one-hour event, “Phineas and Ferb Save Summer.” Just in case an hour of animated adventures isn’t enough, the episode will also feature guest star Jay Leno. The former Tonight Show host will voice Major Monogram’s boss, Colonel Contraction of the O.W.C.A. (Organization Without a Cool Acronym).

From there, the show will have several new episodes, which will include guest stars Jon Stewart, Elizabeth Banks, and Simon Pegg.

The new episodes include “Father’s Day” (June 10), “Imperfect Storm” (June 11), “The Return of the Rogue Rabbit” (June 16), “It’s No Picnic” (June 23), “Operation Crumb Cake” (July 14), and “Mandace” (July 14).

Banks and Pegg will appear in “Imperfect Storm,” with Jon Stewart voicing Mr. Random, president of Random Swimwear, in “Klimpaloon Ultimatum.”

This announcement comes hot on the heels of the Walt Disney World Resort’s sneak peek at the one-hour special, “Phineas and Ferb: Star Wars.” The highly anticipated special is expected to air in July on the Disney Channel and features Phineas and Ferb neighboring the Skywalkers, Doof meeting Darth, and Ferb in training to become an evil Sith. An exact date for the special has yet to be announced.
