I Love Lucy - Season 3 - Eps 3: Lucy and Ethel Buy the Same Dress
Lucy and Ethel buy the same dress for the upcoming talent show for the Wednesday Afternoon Fine Arts League. True, they'll be doing a duet, and their number is Cole Porter's corny "Friendship" but wearing the same dress isn't exactly what they had in mind. Meanwhile, Lucy needs to persuade Ricky to host the show, so she decides to use a little reverse psychology.
