I know what we’re gonna do on Thanksgiving! We’re going to build an [insert something here]-inator!

Oh, and we’re also going to watch the Phineas and Ferb Thanksgiving day episode, starring Gary Cole, Jennifer Grey, Josh Gad, JK Simmons, Stephen Root, and Danica McKellar!

In this episode titled “Doof 101”, Dr. Doofenshmirtz is sentenced to community service for being evil, and much to his daughter Vanessa’s chagrin, he’s assigned to teach science at her high school. Guest starring are Gary Cole as Principal Lang, (Any bets on whether there will be an “I’m gonna need you to come in on Saturday” joke?), Danica McKellar as student Becky, Jennifer Grey as Principal Lang’s assistant Mrs. Pierpont, Josh Gad as bug Wendell, Stephen Root as bug Floyd, and JK Simmons as bug Napoleon.

We’ve also got an exclusive clip of the holiday episode. Take a look:

It’s all going down on Thursday, November 27th (a/k/a Thanksgiving, a/k/a tomorrow) on Disney XD at 8:30pm ET.
