Milhouse Mussolini van Houten is a fictional character featured in the animated television series The Simpsons, voiced by Pamela Hayden, and created by Matt Groening who named the character after President Richard Nixon's middle name. Later in the series, it is revealed that Milhouse's middle name is "Mussolini." Milhouse is Bart Simpson's best friend in Mrs. Krabappel's fourth grade class at Springfield Elementary School, is insecure, gullible, and less popular than Bart. Milhouse is often led into trouble by Bart, who takes advantage of his friend's naïveté, and he is also a regular target for school bullies Nelson Muntz and Dolph, Jimbo and Kearney. He also has a crush on Bart's sister, Lisa, which is used as a plot element in many episodes. Milhouse is one of the few residents in Springfield with visible, in fact rather thick, eyebrows.
