Principal Skinner promises the students that the best-behaved can take a ride in a submarine. Bart believes his past indiscretions will be forgotten. Lisa tries to help Krusty by suggesting him to sell the foreign rights to his shows.

A school trip on a submarine is coming but places are limited and only the best behaved students can go. Bart tries hard to be good but when he feels that Seymour has deliberately cheated him out of his place he and Homer conspire with Seymour's mother to make him think he killed her so he has to leave town. Meanwhile Lisa persuades a broke Krusty to allow foreign actors to impersonate him in their own countries but they prove to be more popular than the original.—don @ minifie-1

Principal Skinner promises the students that the best-behaved among them can take a ride in a submarine. When Skinner gives all the kids a clean slate, Bart believes even his own past indiscretions will be forgotten if he doesn't get into any more trouble. Meanwhile Lisa tries to help a cash-poor Krusty to turn things around by suggesting he sell the foreign rights to his shows.
