The only time the Mertzes' kitchen is seen in the series.
The washer repairman, Joe, is Mrs. Trumbull's nephew. He calls her Aunt Matilda, telling viewers her first name for the first time.
When Lucy is in the kitchen complaining to Ricky about how hard she has to work, lugging the laundry up and down the stairs in the basket, she is alluding to the popular song "Old Man River," from the Jerome Kern-Oscar Hammerstein musical "Show Boat." The lyrics to the song include the following words: "Tote that barge and lift that bale; get a little drunk and you land in jail." Ricky then does call her "Old Man River" after her theatrical tirade.
Mrs. Trumbull's nephew reveals her first name is Matilda.
