Frankie is thrilled when she learns that the Orson Community Theater is putting on a production of "The Wizard of Oz," and that kids don't need to audition to be munchkins, as they will be automatically cast - which is a perfect scenario for a hapless Sue.

Meanwhile, Brick asks his unreliably quirky Uncle Rusty to attend his school's Special Friends Day - with disastrous results.
