Ever since we found out that Forgetting Sarah Marshall scribe and star of How I Met Your Mother Jason Segel was slated to write a new Muppets movie, we’ve been wondering if he could tone down his comedy to a PG level. In an interview with the MTV Movies Blog, Segel responds,

When I get into Muppet mode I turn into a 12-year-old boy. I think them seeing me in those meetings, they had no doubt I would be OK with the tone.

Segel also reveals a special guest star for the movie - Charles Grodin, star of The Great Muppet Caper.
