I Love Lucy - Season 2 - Eps 18: The Inferiority Complex
When no one laughs at her jokes or wants her to be their bridge partner, Lucy comes to the conclusion that she is inferior to everyone else. Worried by Lucy's behavior, Ricky goes to the psychiatrist (or "fizz-a-key-a-tryst" as Ricky pronounces it,) to find the remedy. But it turns out that this doctor's "remedy" isn't exactly what Ricky had in mind.
