History[]
In Bart's future vision, he has been held back in the fourth grade for years. He has a wife and is in the same class as his son. An elderly Mrs. Krabappel asks middle-aged Bart Sr. for the name of the pirate in Treasure Island. When he can't come up with the name, Bart Jr. tells him it's Long John Silver. Mrs. Krabappel then punishes both of them by giving them detention.
