The Middle: The Safe

Frankie is made an example of in front of the entire class when she doesn't make a good impression on her first day of dental assisting school with no-nonsense teacher Mrs. Armwood (Jane Kaczmarek). Meanwhile, because Axl's broken foot may end any chance of his receiving a college sports scholarship, Frankie and Mike insist that he up his grades and get himself a tutor; and Sue and Brick think they've stumbled upon an expensive item inside an old safe and try to get big bucks for it from a local pawn store employee (Rick Harrison).
