Lisa Simpson is the middle child in the Simpsons family and is without a doubt, the most ethical and intelligent member of her family. Lisa excels well in the second grade at Springfield elementary school. A truly gifted child, Lisa not only receives the top grades but is also a talented saxophone player. Her mentor is the now deceased "Bleeding Gums Murphy" whom she had met and jammed with on several occasions. Lisa is considered the "perfect child", which often creates problems for her. Big brother Bart constantly teases her for getting top grades, Homer can't understand why Lisa is a vegetarian, the kids at school think she's a nerdy "brainiac" and Marge is always telling her to smile despite her sadness.
