Events make a person revert to an emotionally younger version of themselves
- President Andrew Shepherd: "She didn't say anything about me?"A.J.: "No, but I could always pass her a note before study hall."
- Briefly poked at in The American President, where divorcee President Shepard found himself attracted to a lobbyist and sought to find some way to pursue a relationship with her without causing too much attention. His attempts ended up making him sound like a middle-school kid wondering if a girl liked him.
- Addressed in full in Home Improvement where a college friend of Tim's was in town, who was not liked at all by Jill. Tim realized that all their time together is spend reminiscing about their "glory days" and trying to re-enact them. Since Tim had a family now he couldn't go off to a bar like his friend wanted to do and the overall message was that true friends grow up with you, which his college buddy did not.
- Made into a major Running Gag in an episode of How I Met Your Mother. Robin's first boyfriend came to visit and despite still being in the same band with no music label backing them and working at a water park to support himself, Robin reverted to her starstruck teenage personality. This lead to a discussion among the group about others who do the same thing, such as Ted having a playful push-fight with his high school buddy Punchy and Lily speaking in heavy street-slang when she meets up with her friend Michelle.
