Milhouse Mussolini van Houten is Bart Simpson's best friend. As the only child of Kirk and Luann van Houten, Milhouse's most distinctive physical traits are his extreme nearsightedness (depicted by very small eyes), requiring thick glasses to correct, and a huge nose about the size of a softball.

Despite being considered a nerd, Milhouse is of average intelligence but has poor social skills. He is also very gullible, thus he is constantly led into trouble by the mischievous Bart, who is not shy about taking advantage of his naive, trusting and loyal friend.
