Lisa Simpson takes after both her parents: she has Marge's common sense, hard work ethic and sympathy for others; she has Homer's last name. Lisa's enormous intelligence and moral authority place her in a unique position in the Simpson family -- and, for that matter, Springfield at large.

Each parents' night at Springfield Elementary, Homer and Marge fight to meet with Lisa's teachers rather than Bart's on the theory that being offered a tin of cookies as thanks is less "upsetting" and "costly" than reviewing quarterly property damage assessments for melted playground equipment. This second grader also plays the saxophone with the virtuosity, if not stubble, of Springfield's late blues great, Bleeding Gums Murphy.
