Lisa Simpson and Luke Stetson

Luke Stetson is Lisa's thirteen year old ex-boyfriend at the Lazy I Ranch. When the Simpsons went to a ranch, Lisa was upset that everybody there was careless. Suddenly, a boy named Luke appears and Lisa takes a liking for him. Luke was unaware of her actions (for he says that Clara had not told him anything), before dumping her after she revealed to him that she had believed Clara to be his girlfriend and thus tried to keep them apart.
