Asian Population Studies  "Asian Population Studies" is the twelveth episode of the second season of the American comedy television series "Community", and the 37th episode of the series overall. It aired in the United States on NBC on January 20, 2011. The study group regathers after the winter break. Annie (Alison Brie) hints that she met someone she likes, and the others try to guess who it is. Shirley (Yvette Nicole Brown) tries and fails to interest them in the fact she is getting back with her ex-husband. Chang (Ken Jeong) again requests to join the group, but Jeff (Joel McHale) flatly rejects him. The group goes for their first class of the semester, Anthropology, taught by a now-sober Duncan. Troy (Donald Glover) accidentally tells Pierce (Chevy Chase) that Shirley had sex with Chang at the Halloween party no one can remember ("Epidemiology"). Doctor Rich (Greg Cromer), Jeff's nemesis from pottery class ("Beginner Pottery"), enters and sits with Annie. Jeff realizes that Rich is the one Annie has a crush on. In the cafeteria, Britta (Gillian Jacobs) realizes a sober Duncan will make the class more difficult. Annie suggests they ask Rich to join the study group. When Jeff objects, Annie suggests they have a mixer and invite a number of people from class to pick one as the next study group member. Shirley's ex-husband Andre (Malcolm-Jamal Warner) shows up. When he goes for ice cream, Britta tells Shirley that she should reconsider her decision, to which Shirley blurts out that she is pregnant and 8 weeks along. Troy and Pierce realize that she might be carrying Chang's baby. At the mixer, Troy tries to find out if Shirley had sex with Andre around Halloween, but fails. Pierce suggests that simply telling Shirley would be kinder to her. Jeff brings a pretty girl named Quendra (Marcy McCusker), hoping that will lure Pierce, Troy, and Abed to ask her to become a member instead of Rich, but something Pierce says makes her storm out. Rich brings kettle corn, instantly gaining popularity. Chang confronts Abed (Danny Pudi) about the fact that he wasn't invited, but Abed just acts like a malfunctioning robot. Eventually, Annie calls for a vote, pointing out that Rich is the only candidate who has stayed. Jeff, desperate to keep Rich out of the study group, agrees to sponsor Chang.
