Superbad’s Seth Rogen will write and star in an epidose of The Simpsons, the show’s creator Matt Groening has announced.

Groening says Rogen has written an episode which features Homer attempting to lose weight to star in a Hollywood movie.

“He wrote an episode we’ll be reading soon, where Comic-Book Guy creates a superhero comic which then gets made into a feature film. Homer plays the lead and to slim down, Seth Rogen will play his personal trainer,” Groening says.

Seth Rogen wrote and starred in Superbad and Pineapple Express.
