Double D compares Ed and Jimmy's relationship to a brotherly one, in which the younger brother mimics and learns from the older one. Eddy uses this observation to take Jimmy under his wing and train him to be more like himself instead of Ed.
Eddy gets a zit, which Double D tells him is a natural part of growing up. Eddy is embarrassed about it and tries to hide from the other kids. Ed finds the zit funny and gets Jonny to come over and see it, to Eddy's dismay.
On a family trip to Cuba, Grampa Simpson becomes depressed and unwilling to partake in activities. He cheers up when he spots an old American car from his times and goes for a ride in it with a native Cuban. Both during and after the ride, Grampa feels reinvigorated and connected with his youth. The Cuban resident references a study conducted by Ellen Langer in which seniors felt young again once exposed to objects from their youth.
