Grandpa teaches Homer and Bart how to be con artists while Marge gets smashed on Long Island Iced Teas.
- Gainax Ending:
Homer: Wait a minute, you're telling me the police force, the TV news, a courthouse full of people, and a popular entertainer had nothing better to do than to teach me and Bart a lesson?
Lisa: I know it seems farfetched, even insulting to your intelligence, but there's a simple and highly satisfying explanation. You see...
Otto: (interrupting) Hey everybody, surf's up!
- Kangaroo Court: Groundskeeper Willie's trial. Willie was the only person in court aside from Homer and Bart who didn't know the trial was a sham to make Homer and Bart confess. He even shot Principal Skinner, who faked his death.
- Of Course I Smoke: After failing to con Flanders, Homer and Bart hide in the treehouse, where Grandpa is waiting for them in a dark corner with a pipe.
Grandpa: Amateurs! [lights up]
Grandpa: That's right!
Bart: You don't smoke a pipe.
Grandpa: That's right! [coughs]
- Riddle for the Ages: Why would so many people (including special guest star Edward Norton) go that far just to teach Homer and Bart a lesson?
- Shout-Out: In one grifting scheme, Homer poses as Ed Mc Mahon and declares Abe the winner of $10,000,000 from "that Publisher's Clearing Dealie".
- Wrote the Book: Abe claims he wrote the book on grifting. Bart checks the grifting book he had been carrying and sees Abe's name.
