According to Jim Recap: No Crime, But Punishment
Gracie is out of control. She just won't listen. So when she is caught writing "boogers" on the bathroom mirror with lipstick (belonging to Dana), it's time that someone puts their foot down. Cheryl thinks that the books are still the way to go. Jim thinks that the books are for stupid people, and something new needs to be tried. He suggests that Gracie has to clean the mess in the bathroom while he eats candy in front of her. Andy agrees, but he would make one change - he wants to eat in front of her too.
