Angry mob of offended young, middle-aged, and elderly women

The angry mob of offended young, middle-aged, and elderly women are a group of women who live in Piqua, Ohio. They only appear in Captain Underpants and the Terrifying Re-Turn of Tippy Tinkletrousers. They are voiced by Len Forgione in the Sound-O-Rama Audiobooks.

Captain Underpants and the Terrifying Re-Turn of Tippy Tinkletrousers
Having moved from Michigan, five-and-three-quarters-year-old George Beard's mother makes him wear a tie as a good first impression. On his way to school, he notices six-year-old Harold Hutchins being attacked by Kipper Krupp and his group, with the mean owner of a gas station, Billy Bill, egging them on. Angered at this, George plays a smart prank on the owner by changing his gas station's sign from "Free Brake Inspection" to "Free Bra Inspection", prompting a group of infuriated and offended women to attack the latter (and maybe even strangle him to death).
