Episode Title: "I Dream of Jeannie Cusamano" (Season 1, Episode 13)
To be clear: there is perhaps no more loved character in the Soprano family than Corrado/Junior, Tony's curmudgeonly uncle who—like Fredo Corleone—is forced to deal with the public humiliation of taking orders from a younger family member. He doesn't deal with it well.
Much of the show's first season surrounds Junior's attempts to de-throne Tony—with the help of Tony's own mother—and reclaim his spot at the top of the mafioso food chain. In the end, Junior fails; Tony finds out about the conspiracy... and yet Junior lives on throughout the entire series run?
