Community (2009)

Cooperative Calligraphy (season 2, 2010) Annie's pen has gone missing, again, and she declares that nobody leaves the room until it is returned. The whole episode turns on who took it, while the puppy parade the group is missing goes on only in everyone's imagination. What lifts it above a clever premise is that Community knows exactly what it is doing: Abed names the bottle episode out loud and keeps up a running commentary on the form, so the episode is both a fine example and a sly essay on why sitcoms make them. Accusations and shifting alliances follow, all without anyone opening the door. If you only watch one entry here, make it this one.
