The family appears as usual, afterwards the angle zooms out to reveal they are on display on as earth humans in a zoo for the alien species to which Kang and Kodos belong.
On Father's Day, Homer is impressed by Bart's gift – a Leather Buddymulti-function knife – but Lisa's gift (a book she created, with caricatures of herself and Homer as unicorns) doesn't go over so well. In a half-hearted attempt to make Lisa feel better, Homer hangs the book on the refrigerator, but it quickly becomes a water-soaked glob of paper.
Lisa takes out her frustrations at school, and her parents are called to talk with Principal Skinner. School psychiatrist Dr. Pryor determines Lisa has a development disorder, which can only be resolved by Homer trying to make amends. He does so by deciding to dress as the SafetySalamander and giving safety talks at school. However, a fireworks display during a school assembly causes a fire.
Meanwhile, Bart – on a dare from the bullies – steals a "Bart Blvd." street sign. This leads to a fiery multi-car pileup when Cletus is unable to find Bart Boulevard. Police cars, fire trucks and ambulances race to the scene but crash into the wreck, making matters worse.
Homer, still dressed in his Safety Salamander costume, runs to the rescue, extricating people who were trapped in their cars just before the pileup explodes in a fireball. Homer gets a rousing reception, and Mayor Quimby is blamed for the bumbling response. Springfield residents pick apart Quimby's administration for other failures, and demand a recall election.
On Lisa's suggestion, Homer decides to run for mayor, playing on his popularity as the Safety Salamander. However, Marge washes the costume, and it falls apart during a debate forum, disappointing the crowd. Eventually, none of the new candidates gain enough of the vote to oust Mayor Quimby. However, Lisa confides in Homer that she is very proud of him and glad he is her father.
None of the candidates win because of less than 5% support. This is in line with "Two Bad Neighbors", where George H. W. Bush says that Springfield has the lowest voter turnout in the country.

The boys stealing The Scream is a reference to one of The Scream paintings being stolen from the Munch Museum in 2004. The Scream itself, however, was first depicted on The Simpsons in Treehouse of Horror IV.
The Station nightclub fire — A pyrotechnics show, which caps Homer's "Safety Salamander" presentation at school, starts the stage curtains on fire, under similar circumstances as the deadly 2003 fire before a Great White concert at The Station nightclub in West Warwick, Rhode Island. Everyone is able to escape the Springfield Elementary School fire, however.
Superman – Homer's line – "This looks like a job for a father trying to win back his daughter's love!" is a play on Superman's signature phrase, "This looks like a job for Superman!"
