There’s another episode in the first season that is made up almost entirely of a flashback to Louie’s days in Catholic school. A nun decides to teach him a lesson for being disrespectful, and brings in a man to re-enact the Crucifixion in alarming detail. He describes what crucifixion does to a human body, he shows off the nails that they would have used, and it’s a real glimpse of horror. Those children are traumatized. And that’s the episode – Louis C.K. only appears briefly, and you can count the number of jokes on your fingers, but it’s absolutely riveting. The most recent episode was mostly built around a long conversation between Louie and Joan Rivers. In fact, Rivers does most of the talking. Louie is reduced to a supporting role. And what she’s saying is legitimately interesting and sort of inspirational. Again, it’s light on jokes, but the ones that are there just killer. Joan Rivers had me gasping for breath by the end, and it was just this perfect half-hour.
