Bart, Lisa, and Maggie live in the small town of Springfield. Bart is famous for being a troublemaker, and his favorite thing to do is to make fun of his dad, Homer, although this sometimes earns him a choking. Lisa, his younger sister, is much smarter than Bart. In fact, she`s smarter than everyone in Springfield. She is very anxious to do the right thing, and recently gave an environmental lecture called “An Irritating Truth” in Springfield`s town hall. Maggie doesn`t say much, but she watches everything, and she may just be the toughest Simpson of all.
