Classic I Love Lucy episode. Lucy's head is stuck in a loving cup, literally. A normal conversation between Lucy and Ricky over what hat she should wear, and it ends up with her putting on the loving cup on her head as a joke, and it turns into a whole premise. Ethel's phone call asking can you get a loving cup out of a woman's head is hysterical. And her saying you won't have trouble recognizing her. I love that even though Lucy has a cup on her head, Ethel is worried she'll be judged wearing her blue jeans at the Subway. Lucy makes a point no one will notice her jeans if she's going with a loving cup on her head.
