For his part, the littlest Keaton has placed his baby boots in the capsule, and asks his parents and siblings to contribute mementos from their past. Soon, the family is looking back and laughing at some of their funniest experiences together, like the time Steven and Elyse went to Woodstock, Alex went to jail with a group of feminists after feigning support for the Equal Rights Amendment and Mallory coached Nick in grammar to pass his high school equivalency exam.

Steven must confront his true feelings about Mallory's boyfriend when Nick moves in with the family for a week. While Elyse struggles to do the family taxes and Steven buries himself in his Tolstoy documentary, Mallory asks her parents if Nick can stay with the Keatons for a week while his house is being painted. Although Elyse gives in to Mallory's pleas, she warns her that Nick must be made to understand that Steven is very busy and should stay out of his way. During the first night of Nick's stay, protective papa Steven parks himself in a chair on the stair landing to prevent any hanky-panky between the couple.
