In the annals of TV Tropes, Chuck Cunningham Syndrome represents the tendency some TV shows have to completely disappear a character with no explanation whatsoever. The fella it’s named after, Chuck Cunningham, was the basketball loving older brother of Richie Cunningham om HAPPY DAYS who one day went off to college and was never heard from again. No postcards, no calls to Mr & Mrs C, no visits during winter break. Old Chuck was just wiped out of the show’s continuity. And he is not the only one…from Bub on MY THREE SONS to Judy Winslow on FAMILY MATTERS to Cockroach on THE COSBY SHOW…characters have been getting wiped from a show’s continuity since forever. So I’ve put together a little list of 5 more recent examples of this phenomena.
