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.
