Lisa Simpson

Lisa Marie Simpson (born May 12, 1983) is a charismatic 8-year-old girl, who exceeds the standard achievement level of children her age. Not to everyone's surprise, she is also the moral center of her family. In her upbringing, Lisa lacks parental involvement of Homer and Marge, which leads to hobbies such as playing saxophone and guitar, riding and caring for horses, and interest in advanced studies. In school, Lisa's popularity is affected by those who view her as a geeky overachiever, which leaves her with only a few friends. Lisa Simpson is a smart, witty, independent girl who focuses on her goals and strives to reach her potential, and at age 8 she is already a member of MENSA with an IQ of 159.
