Parks and Recreation is going a little mad in its final season.

Jon Hamm is set to reprise his brief role as inept National Parks employee Ed, EW has learned exclusively.

The Mad Men star made a surprise appearance in the final moments of the show’s last season finale, when the action jumped three years into the future—and we saw future Leslie (Amy Poehler) terminate Ed, who was somehow a worse employee than even future Larry (Jim O’Heir).

“If I have my way, every episode where you see events that take place before that moment will include a shot of him doing something insanely incompetent,” showrunner Mike Schur told my colleague Dan Snierson of a Hamm return after the finale.

In other news, returning castmembers Rashida Jones and Rob Lowe will pop up in season 7, as will familiar guest-stars Megan Mullally, Natalie Morales and many more.

Parks and Recreation is slated to return for its final season early next year.
