Whit gets on the same elevator as Jean Forbes. Jean then tells Whit how Dr. Frank Graves deserves a medal for how he handled a situation last week...

The Forbes are getting ready for Sunday School while seven-year-old Emily Forbes is watching her loose tooth dangling in the mirror. She doesn't want to pull it out, because she wants Dr. Graves to pull it. It ends up falling out just before they pray for the food. Later at church, Emily, Jean and Bob talk with Dr. Graves. Jean mentions how much Emily loves going to the dentist. She's going to the dentist tomorrow and can't wait for it.

Later that night, Mark Forbes, Emily's brother, decides to scare her by telling her Dr. Graves is going to pull all of her teeth out with big pliers, and how she will get a shot so it doesn't hurt so much. When her parents tuck her in bed, Emily tells them she doesn't want to go to the dentist because she's afraid. Bob tells her she doesn't need to be afraid.

When the big day arrives, Emily is scheduled to go before Mark, and Dr. Graves takes her to the yellow room. She tries to stall and says she should come back when she's not so busy. Then Dr. Graves tells her he was almost finished. Dr. Graves gently gets to the source of Emily's warped information. The good dentist promises not to hurt Emily, and together they devise a plan to turn the tables on Mark, giving him a taste of what it feels like to be afraid. After they scare him, Dr. Graves tells Mark that even though he was just pulling a joke, he hurt Emily by making her afraid of him, making her lie to her parents, and making her dread the whole day. Mark apologizes to Emily, then Dr. Graves tells him "Smile big like a crocodile, Mark!"

Jean finishes her story, and Whit agrees Dr. Graves deserves a medal. Whit then asks why Dr. Graves never asks him to smile big like a crocodile.
