Ever notice a TV show character completely vanish from a popular show and they’re never heard from again? I had no idea it had a name, but it does. Chuck Cunningham Syndrome. You can scroll down and see a list of popular shows where this phenomenon took place and little bit about each one.

In more heinous news, there’s also Cousin Oliver Syndrome. Remember that little bastard? Scroll down and see a list of other shows that played this card to keep the show afloat long after it was clinically dead. I actually shuddered at some of these.

I should hat tip someone here but I honestly can’t remember where I saw it. Probably Dlisted.
