Cousin Oliver Syndrome is the well worn TV sitcom trope of introducing a younger character to the cast of a show in it’s later years as a desperate attempt to add life to a show that had grown a bit long in the tooth. This addition can be successful (like with the addition of Olivia to THE COSBY SHOW) or it can be disastrous like the list that I have put together after the jump. This sitcom trope gets it name from the character introduced in the last season of THE BRADY BUNCH. Cousin Oliver was a horrid addition to the show and never contributed anything of value, instead serving to drive a dagger into the heart of a show that was already on life support. Don’t believe me? Click onward and take a look for yourself.
