I Love Lucy - Season 1 Episode 7 -

Lucy suddenly becomes interested in numerology and superstitions. After advising Ricky that it's a good day for him to make deals, she realizes that she read yesterday's horoscopes and that today is actually a bad day for Ricky. She thus says "no" to a very important business call for Ricky from Mr. Meriweather. In the process of putting things right, Lucy conducts a seance. Classic Ethel quote: "Ethel to Tillie, Ethel to Tillie, come in Tillie."
