While tossing a football with Sam at Goober's service station, Emmett falls into the grease pit. The guys take Emmett to the Doctor and learn he broke his arm. He'll have to wear a cast for 5-6 weeks. Emmett is worried about having to close his shop. Not wanting to leave the town without a fix-it shop, Emmett puts an add in the paper for help. A scientifically-minded high school boy named Ernie applies for the job. Emmett at first turns him down, but then hires him. Emmett soon learns that Ernie is very skilled at fixing things. Word spreads around town about how talented Ernie is and now everyone is bringing in things to be fixed by him. A depressed Emmett tells Sam that he's closing up shop and leaving Mayberry. He says his shop just isn't the same anymore. Sam tells Emmett that even he has to try and keep up with new things and methods. After Emmett leaves, Sam calls the high school. Emmett winds up joining Mr. Desmond's science class at the school.
