Much Apu About Something

"Much Apu About Something" is the 12th episode of season 27. It aired on January 17, 2016.

Plot
Springfield is having a parade in homage to Jebediah Springfield, the city's founder. During the parade, Bart activates a fire engine's water cannon, soaking Chief Wiggum. As a result, the Police Department get into a battle against the volunteer Fire Department, resulting in a SWAT tank losing control, destroying the Kwik-E-Mart, and injuring Apu and Sanjay. At the hospital, Sanjay reveals that he wants to retire form his job at the market and give his share of the store to his son, Jamshed Nahasapeemapetilon.

Seeing the consequences of Bart's prank, Homer decides that Bart has gone too far, and makes him promise to never prank again. Milhouse tries to bring the old Bart back, but he resists dropping a bee hive on Superintendent Chalmers' crotch and releasing the handbrake on Skinner's cherry-picker. But his new personality comes with benefits, as he's now getting better grades, and as result, he's having a closer bond with his younger sister Lisa, as now he understands her point of view for not having any recognition at all for her achievements.

Six weeks after the incident, Apu goes to see what they've done with the Kwik-E-Mart, only to find in its place the Quick & Fresh, a store that sells natural products run by Jamshed (who's now called Jay). In the store's restroom, Jay explains that Apu has an addiction for scatching tickets, and because of that, he's the owner of 80% of the store. Later, Moe and Apu talk about what happened to his store, but Jay, who's already angry at his uncle for being a stereotype, fires Apu from his job. Apu is so depressed that he goes to Moe's Tavern, where Moe convinces Homer to turn Bart back into a prankster for him to pull a prank on Jay so Apu could have his store back.

Bart, who turns back to his old pranking ways a. la. A Clockwork Orange, decides that the best prank would be to turn the Quick & Fresh light switch off for thirty seconds. As none of the products have preservatives, everything will rot, but he's interrupted by Lisa, who reminds him that after he stopped pranking, they love each other even more, but Bart misinterprets the expression "unconditional love" as a sign he can do anything he wants and still be loved by his sister, so he cuts the store's power for a few seconds.

Inside the store, all the products start deteriorating, scaring the customers away, but when he turns the power back on, two hot massage stones collide on top of Apu's jacket, producing a spark that leads to a major fire. As the fireman used all their water and foam against the police on the parade, they have nothing to extinguish the fire with, and the store is completely destroyed by the flames. Later, Apu apologizes to Jay, but he also finds another The Big Bang Theory scratcher ticket in the middle of the debris. He scratches it and wins a million dollars, enough money to buy his store back and rebuild the Kwik-E-Mart.
