As Seen In: "The Grown-Ups" (Season 3, Episode 12)

Roger's daughter is to be wed the Saturday after the assassination of President Kennedy, and the Campbells are not having it. In one of the most human moments between the couple, one that suggests a striking solidarity to their relationship, Pete and Trudy decide to stay home. They curl into each other on the couch to mourn the loss of JFK rather than attend the wedding.

Anyway, they'd only clear everyone off the dance floor with the '60s version of the Percolator.
