Mrs. Rhenquist

Mrs. Rhenquist is Francine Rhenquist's mother.

History
Mrs. Rhenquist was seen with her husband at the '12th annual big science thing' convention, where their daughter was being used in an experiment by Lisa. While her daughter was attacking all the nerds at the convention, she comments to the Simpsons Family that Francine will eventually punch herself out (most likely meaning she will tire herself out). She and her husband have made cameo appearances in other episodes. Her name has never been revealed.

Description
Mrs. Rhenquist wears a fuschia colored dress and pink dress shoes. She also has orange hair.
