The school janitor is constantly getting disrespected by the students. They tease him about smelling bad and compare him to trash. One day one of the students enters the elevator with the janitor. The student holds his nose implying that the janitor stinks and throws empty cup on the floor. As the elevator ascends...it stops all of the sudden, and the lights begin to flicker. The elevator resumes and opens to a teacher belittling the janitor telling him to wipe the counters and mop the floor. Confused, the student exits the elevator and with the mop. He goes into the restroom and looks in the mirror. To his surprise, he's now the janitor. Confused, he begins sweeping the floor. He takes his mop and is waiting for the elevator. While he waits, some students come by to make fun of him. He enters the elevator and the lights begin flickering again. All of the sudden, he sees the janitor in front of him. The janitor bends down to pickup the plastic cup he dropped, but the student picks it up for him. The student then extends his hand to shake the janitor's hand.
