After getting into a fight with his parents, Eddie decides to adult enough to move out on his own. It doesn't take long for Eddie to start regaling his friends with stories about how he can now do whatever he wants, whenever he feels like it, ultimately causing Ward and June to worry that Wally and the Beaver will want to move out as well. However, it doesn't take long for Wally to see through Eddie's stories and works with his new landlady to try and talk Eddie to move back home with his parents.
