Exit question: If she's trying to get rid of the gang, why would she shake her tail feathers in front of them? That might induce them to stay, one would think.
Gene Kelly and Mitzi Gaynor Sizzle in a Diner
Another great dancer in classic movies, Mitzi Gaynor, here partners with Gene Kelly in Les Girls (1957). What the movie, as a whole, lacks in zip and sparkle is regained in musical numbers like this one. Here Miss Gaynor portrays an harassed waitress at a diner and Mr. Kelly is the boorish customer. Of course, they end up enamored with each other.
