S4, E7: 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 (guest star JANE KACZMAREK). Meanwhile, because Axl's broken foot may end anychance of him 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 (guest star RICK HARRISON – Pawn Stars).
