Beverly gets Adam out of the Presidential Physical fitness test; Erica's pen pal visits and Barry tries to impress her.

Adam tries to start a Mel Brooks club after he sees the movie "Spaceballs," and Jackie mistakes his club advertisement for political satire and puts it in the school paper. Meanwhile, when Beverly and Pops come up for parents weekend at school, Erica plans on telling them an important decision she has made, but Murray surprises them and tags along.

Much to Beverly’s chagrin, Barry is thrilled that he gets to celebrate Christmas now that he is engaged to Lainey. Meanwhile, Murray’s brother Marvin makes a promise to Adam with a surprising outcome.

Business rival and nemesis "Formica" Mike attempts to make an offer Murray can't refuse by buying Ottoman Empire. Meanwhile, Adam offers Ms. Cinoman his and Erica's original show when William Penn cannot secure the rights to a well-known spring musical to stage.

Inspired by his obsession, Adam helps Beverly plan a murder mystery party for the family. Meanwhile, Erica, tasked with declaring her major, bumps up against Barry's cockiness as she considers going the pre-med route.

Following Erica and Geoff’s breakup, Murray decides to take Erica out on a daddy-daughter date to cheer her up. Meanwhile, Adam is excited to participate in the school senior prank until his conscience catches up with him and he enlists Beverly’s help to get him out of it.

Erica's world opens when she befriends another young mom; Barry and Adam team up for a money-making performance inspired by a kooky '80s educational entertainer.
