The Big Bang Theory Season 8 Episode 9: The Septum Deviation
5 second plot: Leonard has to have surgery (something with his nose). It's a standard procedure but Sheldon is worried (that Leonard is going to die). Raj's parents split up. He's not taking it well. And it's making Howard and Bernadette think about their marriage.
5 second review: This episode is almost perfect. It's great fun. Only the quibbling between Bernadette and Howard is getting a bit old.
