Homer is fired from the Nuclear Power Plant for ignoring Mr. Burns and chasing after an ice cream truck. When Homer catches up, he chats with the driver Max, who reveals that Homer is his best customer. Homer buys an ice cream and asks for change from a hundred dollar bill. As the ice cream man dispenses the change, quarters at a time, he has a heart attack and then dies, to Homer's horror.
At the funeral, the ice cream man's widow tells Homer to have the Ice cream van, having no need for it herself. Homer hires Otto to pimp out the van whilst he gets dressed in uniform in a style that parodies "Da Ali G show". Homer then goes out to sell ice cream and forces a lactose intolerant boy to eat an ice cream as Homer claims that America is not a country of intolerance. The boy tells Homer to call the number on his medical bracelet but Homer just mocks him for wearing a bracelet.
Meanwhile, Marge is watching "Opal", a talk show. A woman on the show convinces Marge to leave her "Lega-she". Realizing she hasn't done much in her life, Marge is depressed. After Homer leaves a pile of sticky popsicle sticks on the table, Marge fashions them into a sculpture of Maggie. With something to do, Marge begins making sculptures of everyone in Springfield with leftover sticks given to her by Homer.
The next day, the rich Texan expresses interest in Marge's artwork and wishes to finance a show. Marge agrees. as Homer goes out to sell some more Ice cream, Marge stops him and asks that he be at the show for support. Homer agrees and heads off. On his rounds, Homer comes across "Divorced Dad's Visitation Jamboree" picnic. Homer is kept busy most of the day until somebody mentions that it is 3:00, the time of Marge's show. Homer races back home, driving down the side of a hill to escape traffic. The van loses control and tears through most of Marge's sculptures, finally smashing into a tree. Marge is furious and says that Homer couldn't stand that she was a success, Homer says it was an accident but she refuses to believe him, adding that he "doesn't care about anyone's happiness but his own." Homer spends most of the night stood by the bedroom door trying to convince her that he is sorry. He eventually falls asleep and wakes the next day to find out that Marge is gone and left Grandpa to look after the kids, who has been staring at a photograph of the three the whole time. Homer eventually finds Marge a the top city hall and thinks she is about to commit suicide. Marge then explains she is not there to jump and goes on to reveal a huge statue of Homer with pants. Marge has realized that her "Lega-she" is actually a "Lega-we". Homer then asks where she put all the ice cream that was on the sticks she used. Marge says, "In that dumpster over there". Homer dives in and starts eating, until Marge calls out, "Not that one".
200 years later, the statue still stands, an example of the last known art before the fall of Western civilization. We then find out that giant iPods have enslaved humanity, whipping humans with headphones for a hobby.
