"Basic Genealogy" aired on March 11th, 2010. It was written by Karey Dornetto. It was directed by Ken Whittingham.


It’s Family Day at Greendale, so Shirley’s two rambunctious sons, Abed’s judgmental dad and repressed cousin, and Troy’s mean grandmother all come visit.

Professor Slater dumps Jeff, who tries to act like he’s okay with it.

Pierce, who doesn't have family, brings his ex-stepdaughter Amber (played by Katharine McPhee), with whom he has trouble connecting. He enlists Jeff to help him bond with Amber, but instead Jeff and Amber end up sleeping with each other. But when Jeff discovers that Amber is using Pierce for money, he decides to help Pierce rather than run off with Amber.
