A Plot: The "Bevolution" continues, as Beverly decides that she will not go overboard on Thanksgiving this year and instead invites neighbors and friends for a pot luck meal. Bev also refuses to swoop in and help Erica when the latter reveals she got a high-interest credit card at college and has run up $3,000 in debt. Erica then goes to a shady credit card booth, gets a card in Beverly's name, and immediately withdraws a cash advance.
B Plot: Marvin arrives in a decked-out convertible, announcing he has made a bunch of money in the stock market. He ropes the JTP into giving him their money with promises to make them all rich. Barry is excited when Marvin later announces a stock he purchased with the investment has quadrupled, only to be let down when he learns that Murray ordered Marvin to give back Barry's $1,000 before the purchase. Barry scolds dad for his old school thinking, saying he never wants to be middle class like him. Marvin soon announces he lost the JTP's money (plus his own and Erica's cash advance) buying Atari stock, which has tanked due to disappointing sales of its E.T. video game. Coincidentally, Adam has been playing the game and hates it. Barry later sees Murray giving Marvin some money to get back on his feet, and realizes his dad's responsible ways aren't so bad. Geoff offers his life savings to Erica to get her out of debt, but she refuses, saying she needs to be responsible for her own mistakes.
- A Fool and His New Money Are Soon Parted: Barry and the JTP decide to invest with Marvin, despite Murray's warnings. Then it turns out Marvin invested in Atari just as their infamous E.T. the Extra-Terrestrial flopped, and they end up losing all their money.
- Misaimed Fandom: In-Universe, Marvin has fashioned his latest persona on Gordon Gekko from Wall Street, despite Murray informing him that he's supposed to be the villain of the movie.
- The Problem With Licensed Video Games: Invoked. Adam is hit with a hard dose of this in playing the legendarily bad E.T. game.
