After a routine cleaning at the dentist, Kevin gets his first cavity and needs a filling, but feels embarrassed he'll wimp out in front of the pretty denial hygienist Miss Hasenfuss (Whitney Kershaw) and asks Dr. Tucker (Gerrit Graham) if she won't be there. Hasenfuss is then replaced by the much older and hoarse voiced Mrs. Craw (Mary Gillis), making him feel even more uncomfortable. But after Kevin finds out that she's taking his advice on going back to school to become a dentist herself, he has the courage to ask her to assist for one last time.
