God, I can't believe I didn't realize this sooner.
Okay, so on "Arrested Development," Michael (Jason Bateman) is the third born child of the Bluth family. (They mention in one episode that his twin sister Lindsay came out first.) Michael hates the family business and constantly wants out, but family politics keep pulling him back into the mess he was born into. Despite not being the oldest, his father ends up passing the business onto Michael anyway. A big reason for this is that GOB is a playboy and Buster is a little slow. In turn, his brothers and sister scramble for favors.
Coincidentally, "The Godfather" centers around Michael Corleone (Al Pacino), who is also the third born. He also hates the family business, but ends up assuming the position of patriarch anyway. His siblings also scramble for favors from him. Michael also has a brother, Fredo, who's a little slow, as well as one sister. (It should be noted, however, that a big reason for Santino not being the heir to the family business is that he is assassinated, not an idiot. Like GOB. GOB is an idiot.)
