How to Lose a Cajun in 10 Days

In 2003, the romantic comedy "How To Lose A Guy In 10 Days" was released starring Kate Hudson and Mathew McConaughey. In the movie, McConaughey's character Benjamin Barry is an advertising executive and ladies' man who, to win a big campaign, bets that he can make a woman fall in love with him in 10 days. Feelings and hi-jinx ensue, and everyone is happy in the end. I guess I'm not completely sure. I've never seen it but I'm sure it's a fine film. The movie's title got me thinking, what things would someone have to do or say to lose a Cajun in 10 days?
