See images of Pamela Hayden, Glenn Close, the voices of Mona Simpson in The Simpsons (TV Show). Mona was strong-willed, righteous and caring, always doing what she knew or thought was the right thing no matter what. She cherished the relationship she had with her son and later her grandchildren and daughter-in-law. Despite her friendly nature, she was shown to hold distaste for her ex-husband and Homer's father Abe due to his irritability, intolerance and questionable parenting methods concerning their son, even berating him for telling Homer she had died. She also disapproved of those with ill intentions, as seen when she joined a radical group protesting biological warfare experiments and other unscrupulous activities by Charles Montgomery Burns. Her voice matches that of Lunchlady Doris, rather than her soft, Southern voice she had when she was first introduced. In "Krusty Gets Kancelled", she is again briefly seen in the center square of Springfield Squares.
