After overhearing Ellen moaning like a porn star, Louie asks Walter for sex tips, only to learn he's been out of town all week. Left to his own devices, Louie sets out to up the ante — and the volume — with Kim, and miraculously triggers her first orgasm. But when they try to recreate the magic, Kim's orgasm eludes them. Since it took Kim 37 years to "unlock her box," Louie wants to forego baby-making until they figure out their formula and she has consistent orgasms. Across the hall, Walter confronts his wife, only to discover she's been cheating on him with a vibrating piece of plastic, a "goddamn made in China motherf@%ker."
