Mr. Bergstrom

Mr. Bergstrom was Lisa's substitute teacher. Mr. Bergstrom took over for Ms. Hoover after she believed she had Lyme Disease and Lisa immediately took to him because he was the kind of male role model she needed in her life. However, after Ms. Hoover returned, he had to leave Springfield. A distraught Lisa ran to stop him, and Mr. Bergstrom gave her a note saying "You are Lisa Simpson". The note appears one more time in the episode "Smart and Smarter", in which Marge gives Lisa a paper that says "You are Lisa Simpson" and then Lisa says "I already have one of those".

About Mr.Bergstrom
He, like his voice actor, Dustin Hoffman, is Jewish. He is an artistic, liberal teacher who tries to inspire his students, even though that means some will make fun of him, by drawing a picture of him with his guitar and naming him "The Singing Dork". Instead of being offended by this, however, he laughs and asks Lisa if he may keep it. Lisa says she did not draw it, although his praise of the art makes her wish she did. Mr. Bergstrom also encourages the students to patronize the Springfield Museum of Natural History, as it will soon be going bankrupt. This inspires Lisa to visit, and Homer is grudingly made to chaperone her. Mr. Bergstrom encourages Homer to think more highly of himself, as he is the only man in the world who is Lisa's father.
