The corn starts popping when Tennessee Ernie Ford comes to visit in Part 1 of a two-part episode. He's Lucy's "Cousin" Ernest, an earnest young man from Bent Fork, Tenn., who knows nothing of city ways and is inadvertently infuriating. He's got to go but he's so sweet that they can't just throw him out. What to do? Lucy will pose as a wicked city woman, and "vamp" him out of town. (thetvdb.com)
