This was one of the better episodes of "The Simpsons". It is a great parody of Elizabeth Holmes "Theranos". Burns backs and marries Persephone Odair (Elizabeth Banks) who has invented a black box the size of a coffee can ("Lifeboat") that convert sea water into drinking water. As I mentioned, there are obvious parallels to the Theranos debacle with the methodology being secret and clandestine efforts to uncover the truth behind the mystery of how the Lifeboat product actually works. Of course, there is a whistleblower to bring out the truth. With guest stars including Andrew Ross Sorkin, Ken Burns, Peter Coyote and Kara Swisher as part of the story, I laughed out loud several times. I was surprised to see the relatively low rating for such a standout episode. Why anyone would rate this episode below a 7 or 8 defies my imagination.
