During the holiday, Uncle Marvin reveals he has become a stockbroker and convinces Barry and the JTP to invest their money with him. Meanwhile, Erica tells Geoff she is in debt and gets swept up in the family investment. Later, Beverly invites 50 people over for a Thanksgiving potluck instead of stressing out cooking for the family.

Barry realizes that as a future doctor, he should be more concerned about Murray's health, so he enlists the Jenkintown Posse and Coach Mellor to help get his father in shape. Meanwhile, Beverly is horrified to learn that Erica and Adam don't want any of the priceless heirlooms in her fancy, never-really-used living room.

Adam is thrilled when he has to design his own video game for school, so he turns to his family for inspiration. Meanwhile, Beverly is worried about Pops’ gambling and ropes Bill Lewis into her latest scheme.
