 At the crossword tournament, Homer bets his money from his breakup business on Lisa and wins big. However, upon hearing Lisa saying that she is wary of the final round, he bets on the other finalist, Gil Gunderson. Gil plays Lisa for her sympathy and cons her into losing the round, which in turn lets Homer win his final bet. Upon realizing that Homer has come into some money by betting against her in the tournament, Lisa gets angry at him and refuses to acknowledge herself as Homer's daughter, even going so far as to take Marge's maiden name and start calling herself "Lisa Bouvier". Feeling guilty, Homer commissions Merl Reagle and Will Shortz to create a special puzzle for the New York Times, with his apology to Lisa hidden in the clues and solution. The two of them make up, and Lisa is happy to call herself a Simpson again.
