Sexuality Lisa's sexuality has become the subject of speculation amongst viewers of the show. Lisa is shown to have heterosexual crushes on Nelson Muntz and Langdon Alger in "Lisa's Date with Density" and "Bart on the Road" respectively. In some episodes Lisa is shown to have a boyfriend, such as Edmund Dracula in "Treehouse of Horror XXI" or Colin in "The Simpsons Movie". Lisa becomes engaged to, and later almost marries, Hugh Parkfield in "Lisa's Wedding" and the episode "Holidays of Future Passed" suggests that Lisa will go on to marry Milhouse Van Houten. However, "Holidays of Future Passed" also show Lisa being in both a monogamous, and later polyamorous, lesbian relationships.
