Mrs. Muntz

Mrs. Muntz (voiced by Tress MacNeille) is Nelson Muntz's mother. Nelson receives his trademark laugh from her. Early on in the series, Nelson would often mention his parents, and it was often implied that Nelson's mother does not care for him. In "A Milhouse Divided", Nelson tells Milhouse that his mom got hooked on cough drops, which is why his father left the family. In "Bart Star", it is stated that Mrs. Muntz works at Hooters as one of the waitresses. She owns a dilapidated house and is depicted as a jailbird, a whore, a stripper, or something similar. She was first heard (but not seen) on the season ten episode "Wild Barts Can't Be Broken" when Nelson goes to break curfew and she yells, "We're out of Skoal!"

Her first visual appearance was "'Tis the Fifteenth Season" when she tells Nelson that his father simply did not like him, and he left with her golden tooth. Nelson's mother was more introduced in "Sleeping with the Enemy". A loud, high-pitched contemptuous woman, Mrs. Muntz neglects Nelson. She implies she misses Nelson's father. At the end of the episode, the three Muntzes reunite, and she receives a new job as Lady Macbeth, with "the third director she slept with" ("I don't have to take my top off, but I do anyway!"). Since then, she is often seen around in Springfield. Curiously, in Season 18's "The Haw-Hawed Couple", she appears with brunette hair. As revealed in "Dial 'N' for Nerder", Nelson even refers to her as Mrs. Muntz.
