Opie complains to Andy about how his new history teacher Ms. Crump is a mean old woman who likes to assign extra homework. Andy tells Opie it's not important if he doesn't know every answer, which leaves Opie believing history isn't important. Now Andy has to show Opie, and his class, how much history matters before Ms. Crump decides to quit.

Opie and his friends decide to play Robin Hood to a friendly hobo they meet in the local woods and take food from their own cupboards to give to him. Andy decides to meet the man and ends up teaching them all a lesson in who the rich and poor really are.

After becoming jealous of the attention Andy give to the new boy in town, Opie comes to Andy wrapped in bandages and tells him he and the new boy got into a vicious fight. One peek under Opie's bandages, however, tells Andy the fight may not have been as bloody, or as real, as Opie says.

When Opie and his friends are scammed into selling a useless skin ointment, Barney and Gomer try to help convince the company their product is more valuable than they think. When the scheme backfires, however, the whole gang learns a lesson in the art of the deal.

While on a camping trip with Opie and his friends, Barney brags to Gomer about his outdoor skills and promptly gets them lost in the woods. When Andy finally does find them, he and Gomer hatch a plan to save Barney the embarrassment and prove to everyone what a mountain man he really is.

New height and weight requirements go into effect for all law enforcement officers, which threatens to put Barney out of a job unless Andy can figure out a way to throw around some much-needed weight.

Andy catches Opie trying to sell his broken bike to a friend and teaches him a lesson in honest dealing. But when Barney talks Andy into selling his house, the lesson comes to haunt him as Opie points out all the faults of the Taylor house to Barney's potential buyers.

Opie and his friend decide to spice up the newspaper they've started with a gossip column, which works great until Andy and Aunt Bee realize it's mostly about them.
