Green Acres

Inspired by a cheesy "Zorro" movie, Homer begins slapping people with a glove and challenging them to duels (with the victims giving Homer whatever he wants instead of accepting the challenge), but when a real Southern gentleman accepts Homer's request for a duel, the Simpsons run off to the old farm Homer lived in with his parents (as seen in the season six episode Grampa vs. Sexual Inadequacy) and breed a dangerously addictive but successful tobacco/tomato hybrid called "tomacco". Just when they are about to gain a hundred million dollars from the hybrid, dangerously addicted animals ruin their plan. Homer proceeds to duel, only to get shot in the arm.
