Rob Corddry has a grand plan… to become head surgeon!

In ETonline’s exclusive sneak peek of the season-six finale of Childrens Hospital, Blake (Corddry) marches into the hospital executive office with the mission to become the newest head surgeon, even if that means subtly (and hilariously) throwing his co-workers under the bus.

The two-time Emmy-winning Adult Swim Series features a star-studded cast consisting of Rob Huebel, Ken Marino, Megan Mullally, Michael Cera, Erinn Hayes, Henry Winkler, Lake Bell, Zandy Hartig, and Malin Akerman.

“These guys are only doing it because it's fun, certainly not because they're making any money!” Corddry told ETonline at the start of the season. “They make time in their schedule and in their heart you know? They're just full on -- it's so great.”

The season finale of Childrens Hospital airs Friday at midnight on Adult Swim.
