Lisa becomes the anchorwoman for a children's news program. Bart is also hired for the show and launches a series of trite human-interest stories that attract a lot attention and overshadow Lisa's more serious work. Meanwhile, Homer claims he's handicapped so he can adopt a trained monkey named Mojo, who will wait on him hand and foot. As Bart's star is on the rise, Lisa devises a plot to destroy his career by having him do a segment on Groundskeeper Willie, who hates Bart for destroying his shack. Lisa gets more than she bargained for when Willie tries to kill Bart. She saves Bart's life using the same soft, human-interest speak that her brother pioneered in his segments. Back at home, Mojo has become fat and lazy after emulating Homer's ways. Homer returns Mojo to the animal shelter and learns to fetch his own beer again.
