The scene: Nightclub singers Dorothy Shaw (Jane Russell) and Lorelei Lee (Marilyn Monroe) are boarding the Ile de France to sail to Europe. Lorelei has just become engaged to Gus Esmond (Tommy Noonan). Dorothy is expected to protect Lorelei's virtue during the trans-altlantic crossing.

As they board the ship, Dorothy heartily admires a group of Olympic athletes.

Gus: Dorothy Shaw, you're supposed to be the chaperone on the trip!
Dorothy: Now let's get one thing straight, Gus: The chaperone's job is to make sure nobody else has any fun. But nobody chaperone's the chaperone. That's why I'm so right for this job.
