In celebration of the last day of school, Bart wakes up the family by banging pots and pans together. Even though Homer initially says that he has a plan of making Bart go to summer camp, Marge points out it's a prison road crew in the picture.
Bart interjects that he did that last summer, and he's not allowed back.
The family convenes in the kitchen, where Homer discovers while reading the local newspaper that the Fourth of July fireworks has been cancelled due to the fact that the city is broke.
Meanwhile, Springfield Elementary has their annual Field Day festivities, where kids learn to balance eggs on spatulas and have their ankles tied to someone who don't care two cents about them.
During the egg toss, the objective is to make it across to one's partner, but each pair hurl it at Principal Skinner.
“Look, do you want this to be your last school memory?” asks Skinner.
The kids hurl the eggs at Skinner once more.
The race around the school prompts everyone to do the best, including Milhouse, who has been practicing for this race. Milhouse reveals to Bart that he has been training as Martin overhears this secret.
As each student runs during the race, Milhouse leads the pack before Nelson and the bullies plan to knock some sense out of him.
When Nelson awaits for Milhouse at the pivotal turn of the race, he hands Milhouse a cup of water before hitting him. Bart sees this, but runs ahead of the race to win first place.
After Bart receives a blue ribbon for first place, Milhouse emerges from the bushes with amnesia conveniently.
Although Bart has several opportunities to disclose to Milhouse that he could have won the race with the help of his best friend, Bart lets that opportunity slip by even at a town ceremony honoring him.
However, when one of the bullies slingshots at Milhouse's forehead, the memories come rushing back to where Bart just stood idly by as Milhouse suffered beating after beating.
Outraged townspeople chase Bart off from the ceremony. Bart runs to the retirement home to seek help from Grandpa without much luck.
Elsewhere, Homer finds a man from the past to execute a spectacular fireworks display for the town, but a fight breaks out.
The fireworks go awry, yet Bart quickly thinks on his feet to get the town to believe that Milhouse is the modest hero.
The Simpsons returns in the fall on Fox.
