The Simpsons: 15 Huge Guest Stars & Cameos You Forgot
11. Winona Ryder
Not only has Lisa always been by far the smartest in her family, she had gotten used to being the smartest in her class, and in the entire school. In fairness, the likes of Ralph Wiggum didn't really give her a run for her money, so when Allison joined her in Miss. Hoover's class, Lisa started getting competitive.
Not only was Allison younger than Lisa, she was arguably smarter, and arguably better on the saxophone. The voice behind Lisa's rival was that of Winona Ryder, who was able to lend a young, yet sophisticated quality to Allison in her battle with Lisa.
Not that she was even aware of Lisa's disdain for her. With the help of Bart, Lisa was able to passive aggressively sabotage Allison's science fair project before they eventually became friends.
Though the episode ended with the two second graders on the same side, Allison was very rarely seen around Springfield Elementary again, and on the even rarer times that she spoke, it wasn't Winona Ryder's voice but either Maggie Roswell or Pamela Hayden.
