Sadie just realizes she can’t run the big Donut herself so Steven volunteers too help her and Sadie deputizes Steven as her "Lars of the day". Sadie shows Steven the break room, and reveals she and Lars watch TV together and sometimes Lars even covers for her so she does not miss her show. Sadie then shows Steven the instruction video featuring Harold Smiley singing Do or Do Nut. Sadie jokingly says that Steven should be Lars' replacement, but Steven takes her seriously and asks Sadie to fire him. Sadie tells Steven that despite his faults, she thinks Lars is a good guy once one gets to know him. She explains to Steven that when a video game Lars wanted had come out, Sadie stood in line for seven hours for him since he was banned from the store.

This gives Steven an idea of how to burn Lars and the next day, Steven introduces Sadie to Fire Salt to prank Lars. Sadie is initially against it until Lars walks into the Big Donut, still faking the injury to try and get another day off. Sadie gives Lars a donut laced with Fire Salt, which causes his face to swell up and violent breathe a stream of fire. Lars panics and flees the store and looks for anything to cool his mouth down with while Sadie scrambles to put out the fires with a fire extinguisher.

Sadie stops Lars, telling him she planned it in revenge for lying to her and making her think he was a good person since that night they played video games. When the fire finally stops, Lars struggles to speak. Steven gets the fire donut out of Lars' throat by pushing below his diaphragm.
