 Relationship with Mayor Quimby
Martha is well aware that Mayor Quimby cheats on her; she only stays with him because she enjoys the power that goes with being the mayor's wife. Martha puts up a brave front of being all right with the mayor's cheating, but on one occasion she revealed her true feelings. Marge Simpson was visiting the Quimby house and talking to Martha in the mayor's home office. Martha accidentally pressed a button that transformed the office into a combination bar/strip joint, and broke down in tears at the sight of scantily clad women in cages being lowered from the ceiling.
 Behind the Laughter
Like Sarah Wiggum and Bernice Hibbert, Martha is one of the less notable and more sane characters on the show. Also like Mrs. Wiggum and Mrs. Hibbert, Martha plays the role of the quiet housewife, the wife to a corrupted husband.
Martha often wears a pink suit and pillbox hat, a style similar to the one that Jacqueline Kennedy made famous.
