When Homer humiliates Marge at a party they've thrown for their friends and neighbors, the only thing that can save their marriage is a weekend retreat for married couples run by Reverend Lovejoy up at Catfish Lake. Marge is determined to fix their marriage, but Homer is more determined to catch General Sherman, the freakishly large catfish that lives in the lake. Marge tells Homer that if he really loves her, he won't spend any time fishing, but while taking a walk along the lake one morning, Homer finds himself unable to resist the chance to catch General Sherman. When Marge finds him wrestling the gigantic fish into a boat, she scolds him for lying to her. Homer proves his love for Marge the only way he can: He lets General Sherman go.
