Milhouse and Bart Simpson are best friends who are constantly getting in trouble for Bart's stupid ideas.
Milhouse is pretty much a follower, as opposed to a leader. His parents are divorced, and his father is pretty much as unsuccessful as it gets. For instance, his dad sits at home in his underwear crying & making jiffy pop on the stove.
His mom has actually moved to Capitol City, and Milhouse went to live with her for a short time.
Millhouse and Bart once ran the Android's Dungeon & Baseball Card Shop, when Comic Book Guy had a heart attack.
