Mrs. Grouch is the mother of Oscar the Grouch in the long-running American children's television series Sesame Street (1969–). Mrs. Grouch has visited Sesame Street various times over the years, including in episode 3141, to make sure that her son is still Grouchy, and hasn't been turned nice. That same year, she also appeared in the special Sesame Street Stays Up Late!, communicating by telephone with Oscar and other relatives. In a later visit to Sesame Street, she was performed by Leslie Carrara-Rudolph. After she arrives in that episode, she & Oscar greet each other in a very normal Grouchy way (Oscar: "Rotten to see ya, Ma." Mrs. Grouch: "Ah, rotten to see you too, son. Heh heh heh!"), which is how Grouch families tell each other that they really are happy to see each other.
