Roman DeBeers is ditching the catering biz for a gig at Greendale Community College.

TVLine has exclusively learned that funnyman Martin Starr will guest star in the third season of NBC’s Community (premiering Thursday, Sept. 22). When Jeff Winger and Co. venture into the fun-filled world of Model UN simulations, the Party Down scene-stealer pops up as their fearless poli-sci professor and project advisor. Starr may return to the quirky comedy later in the season, but as of now, it’s a one-off appearance in Episode 2.

I’m hearing this bit of casting came about after Community‘s Alison Brie began shooting her new movie, Save the Date, with the actor earlier this summer — a flick which just so happens to feature yet another Party alum, Lizzy Caplan.

Starr can currently be seen opposite Paul Scheer (The League) on Adult Swim’s new live-action procedural spoof, NTSF:SD:SUV.
