Stan (Moaning Lisa)

Stan is a student at Springfield Elementary School. He plays in the school band.

History
Once when Lisa was very depressed, Marge told her that she shouldn't show her sadness and should instead put on a smile. Lisa then faked a smile, got out of the car and walked up to the school to go to band practice. Stan noticed her smiling and invited her over to do his homework, saying that before he thought she was weird for being sad. Lisa agreed and Marge, seeing how her advice was not very good, drove up and pulled Lisa back into the car, telling her that it's more important to express her feelings instead of bottling them up.
