No, it's not a Breaking Bad/The Office crossover - we already got one of those - but it's close enough: According to a tweet from Office star Rainn Wilson, Walter White himself, Bryan Cranston, is on the set of the long-running NBC show to direct an episode for the upcoming season. Accompanying the Instagram photo is the caption "Free meth for The Office! (look who's directing...)." This, coupled with the Arrested Development reincarnation? Be still our TV-loving hearts.

The Office returns September 20 at 9 PM.
