This episode pits a pair in their late 40s against a pair in their early 20s. The older pair repeated complains about having to merge up with millennials. Even after meeting the remaining younger member (Amanda), Joe continues to call her a millennial. Someone in there early 20s when this was made would be an older Gen Z aka a "Zoomer", not a millennial. Millennials would be in their late 20s-late 30s. Similarly the title of this episode is "OK, Boomer", and the older team is actually Gen X.
