On last night's episode of The Simpsons , Lisa became a crossword addict. She became so good that she entered into crossword competitions, and Homer saw it as an opportunity to make money by betting against her. After finding this out, Lisa got so pissed off that she changed her last name to her mother's maiden name Bouvier, and Homer realized that the only way he could communicate with her to apologize was to through a crossword puzzle, so he got famed New York Times crossword editor Will Shortz to help him.
