VIDEO: Sneak Peek - 'Pawn Stars' Rick Harrison Guests on ABC's THE MIDDLE

On this week's episode of the ABC comedy THE MIDDLE titled "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, "Malcolm in the Middle"). 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, "Pawn Stars").
