Beginning of the Chuck Cunningham Syndrome
Have you ever wondered what happened to your favorite character who suddenly disappeared from a show you loved? Well, even if we cannot always explain what went down with your beloved character, there is a name for that phenomenon where a TV star leaves a show without a trace.
It is called Chuck Cunningham Syndrome which is named after O’Herlihy’s role in Happy Days. In one episode he went upstairs and then never emerged from the stairs again. Hence the name, to explain the unpredicted disappearances of the stars from their roles in the TV shows.
