The town is excited about the Baseball Class "A" Excursion. While buying his ticket, Goober complains to Sam and Andy about the contents of the box lunch that will be included. Mike is excited to be going to the game. Sam becomes upset with Mike for losing a second jacket in less then 10 days. Mike has also lost several other items lately. Sam tells him that if he loses one more thing, he can't go to the game. Mike is playing baseball with some friends and he loses his watch. Mike tells Sam what happened and Mike knows he can't go to the game. Sam feels bad about enforcing his rule. It doesn't help that many townspeople are giving him a hard time about it. Andy gives Sam an idea of how he might be able to let Mike go to the game. Sam buys a similar watch and then sets it up so Mike can find it. While watching the game, Mike finds his original watch in his baseball glove. Mike realizes what his father did for him.

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.

At their lodge finance meeting, Sam discusses their new health insurance plan. It will only increase dues $8 a month and all bills will be paid by the lodge. Later, Howard tells Sam that his doctor suggests he have an operation to correct his deviated septum. Elmo finds the timing of this operation very suspicious. Emmett and Goober confront Howard and call him a crook. They go with to the hospital to make sure Howard doesn't pad the bill. Emmett and Goober then ask Dr. Wilson about some of the expenses of the operation. Emmett and Goober decide to go see Howard at checkout time to make sure he doesn't stay longer than he should. The lodge meets and learns the health fund is heavily depleted. Goober suggests if Howard doesn't have appendicitis the lodge shouldn't pay for the extra day. Howard is out of the hospital. Goober doesn't believe someone can develop symptoms just by talking about it. Then Sam mentions hives and Goober starts itching.

Goober finally opens his new gas station in Mayberry! Everything goes fine and dandy until Howard discovers some old reltics under the gas station- DINOSAUR BONES! He is eager to recover them, but recovering them would mean tearing parts of the road around the gas station, and Goober won't allow it! Howard wants to make a mueseum with these bones, but wants to get all of them, so he sneaks to the gas station in the middle of the night. And he's caught! Gooober almost presses charges! Howard then opens the first natural science muesum ever in Mayberry, but it's a bust, because most of the bones from the dinosaur are still buried. Seeing how upset Howard is, Goober has the other bones recovered and all is once again well in Mayberry.
