So that the host won't recognize her from her previous show-destroying appearance, Lucy passes herself off as a dark-haired Italian floozy named Lucrecia Carmucci.
The name of the TV program Lucy and Harry Tuttle appear on is The Talent Discoverer's Show.
This is the first episode in which Vivian Vance does not appear. She was unhappy having to constantly commute to the West Coast just to play a supporting role. To help make her happy, she was given additional weeks off during the season so she wouldn't have to make the trip as often.
