Huebel will play Jerry, Chris' (Will Arnett) annoying roommate from college that he can't seem to get rid of. After reluctantly accepting an invite to one of Jerry's parties, Chris brings Ava (Maya Rudolph) along to help buffer him from Jerry's inevitable rants about whatever fad-of-the-moment he's into this month.

The 43-year-old actor — whose credits include The Office, Modern Family and Human Giant — will appear in the fourth episode, slated to air Oct. 11.

Up All Night returns Thursday, Sept. 20 at 8:30/7:30c on NBC.
