S4, E23: While waiting in line at the power company to pay a late bill and dressed in her lab coat for her new dental assisting job, people mistake Frankie for a doctor and let her cut in front of them so that she can finish her business quickly and get back to saving lives. But when one of those people shows up at Dr. Goodwin's (guest star JACK McBRAYER – 30 Rock) office for a dental checkup, Frankie must attempt to keep up the charade, which leaves her new employer completely perplexed. Meanwhile, Axl discovers that Sue has a perfect attendance record at school and convinces her to ditch a day and live life on the edge; Dr. Fulton (DAVE FOLEY) tries to find out why Brick is so opposed to going to middle school; and Mike and Axl's fishing trip takes a turn for the worse when a distraction causes Mike to crash the boat he is towing, wedging it into a ditch.
