Dustin Hoffman as Mr. Bergstrom (credited as Sam Etic)

"Lisa's Substitute" is the nineteenth episode of The Simpsons' second season. It originally aired on the Fox network in the United States on April 25, 1991. In the episode, Lisa falls for her inspirational substitute teacher Mr. Bergstrom, while Bart runs for class president against Martin.

Jon Vitti wrote the episode and Rich Moore directed it. Dustin Hoffman—using the pseudonym Sam Etic—guest-starred as Mr. Bergstrom, who was modeled on the physical appearance of Mike Reiss, a longtime writer and producer on the show. The episode features cultural references to Mike Nichols's film The Graduate, which starred Hoffman, and the novel Charlotte's Web by E. B. White.

The episode has received mostly positive reviews. It acquired a Nielsen Rating of 11.1, and was the highest-rated show on the Fox network the week it aired.

Lisa's teacher, Miss Hoover, thinks she has Lyme disease and is replaced by substitute teacher Mr. Bergstrom. Because of his unorthodox teaching methods and friendly nature, Lisa starts falling in love with him. Lisa runs into Mr. Bergstrom at a museum and is embarrassed when Homer displays his ignorance. Sensing a void in their relationship, Mr. Bergstrom takes Homer aside to suggest he be a more positive role model.
