Jerri Mackleberry is the mother of the twins Sherri and Terri. She looks very similar to them, but she wears glasses. Her appearance in the 1991 Butterfinger Ice Cream Bars commercial is different from that in the series as she does not wear glasses and has her hair styled in a similar fashion to that of her daughters. She has one voiced appearance in "The Daughter Also Rises," although it is unknown who voiced her. She is whiter and less yellow than her daughters.
