Homer begins challenging everyone around him to duels after he sees a Zorro film at the Googoplex. Most people back down, until Homer meets an old-fashioned Colonel who takes him up on his dare. Unable to get out of the contest with the Colonel, Homer and his family flee to the country, where they become farmers. Farm life is difficult until Homer creates a new crop called tomacco--tomatoes crossed with tobacco. The new fruit is disgusting to eat, but incredibly addictive. Selling barrel upon barrel of tomacco, Homer attracts the attention of some tobacco industry executives who want to capitalize on his new crop. Will Homer sell his cash crop for a pile of cash? Why are all the animals who ate tomacco suddenly going berserk? Would it really have been so bad to duel that Colonel after all?
