If a Man Answers is a 1962 American romantic comedy film directed by Henry Levin and stars then real-life husband-and-wife Bobby Darin and Sandra Dee.
A spoiled rich girl, she goes after Gene, and he responds positively to Tina's flirting tactics, making Chantal start to become nervous about her marriage.
Tina continues to stir up trouble, by admitting in a drunken stupor that she is desperately lonely and envious of Chantal's marriage and telling Gene about the dog-training book.
She kept up the act by sending herself flowers and having her girlfriends call and hang up "if a man answers" the phone, resulting in making her husband jealous.
Before Chantal leaves to go home to try out these techniques, her mother tells her that whenever Gene confronts her, she needs to respond honestly; this would make him wonder if his wife is really telling the truth about having an affair (despite being told all about the trick, John still genuinely wonders if Robert Swan exists).
All of this seems to work, after Chantal periodically sends herself two-dozen white roses and has her mom call in and click the receiver when Gene picks up the phone.
Chantel goes to explain the entire situation, but Gene still pleads with her to end her affair, making her wonder why her mother's old tactics did not turn out as planned.
To add to her confusion, Gene actually invites a "Robert Swan" to dinner and then asks him to move in and share Chantal in a polyandrous relationship.
Germaine finds out from John that he, Gene, and Adam were all in on the "Swan" act from the very beginning, to which she "admits defeat" and commends her husband for "being loyal to his sex."
