I Love Lucy - Season 4 Episode 13 -

The Ricardos and Mertzes head for California. But first, of coures, there are complications. The chief one: Lucy's mother, who shows up and wants to accompany them. Ricky objects (to put it mildly), and when Fred and Ethel overhear him complaining about too many people on the trip, they take it personally. And when the dust from that blowup finally settles, there's packing to do.
