During Lunch , The Janitor sells “biscut balls” for 1 dollar a piece. The Janitor says that the biscut balls are made of "Whatever's in a biscut and a little something extra." For some reason, The Janitor wants Cindy to try one. During lunch, Monty says "I don't think anyone is brave enough to try a 'biscut' from the Janitor. Dumb old man can't even spell it right." Then you can tell the Janitor that he spelt biscuit wrong. Then you tell him Monty was the one who told you that biscuit was spelt wrong. Then, The Janitor will proceed to knock Monty out.
If you take a note from the Janitor's Closet, getting someone to read it will reveal that Cindy's dog Biscut was likely killed by The Janitor and is the "secret ingredient" of the biscut balls. If you tell this to Cindy she will kill the Janitor by ripping off his ear and then his head.
