Fiona volunteers to run a project for Marcus's class - a miniature society modeled after Dickensian London. Wanting to be King of the mock economy, Fiona instead selects him as the lowly slopmaster, much to his dismay, prompting him to figure out a clever yet questionable solution to turn things around. Meanwhile, Will takes Marcus out on a spending spree, thanks to his latest royalty check and then does his best to throw the perfect party to impress Sam.
