You huffed. You hollered. You harangued. And in the end, you got your wish: Community will return to NBC next Thursday after a three-month hiatus with an all-new episode. Nope, not part-new. All-new. In “Urban Matrimony and the Sandwich Arts,” Andre (Malcom Jamal Warner) re-proposes to Shirley (Yvette Nicole Brown), who also teams up with Pierce (Chevy Chase) to sell Dean Pelton (Academy Award winner Jim Rash!) on a sandwich shop for Greendale’s caf. In other words, Shirley has a lot going on. If you can’t wait until next Thursday — and who can? — check out this clip, in which the gang sit around a table, discussing Shirley’s big news. Come for the romance, stay for Britta (Gillian Jacobs) trying to define an analogy.
