August 7, 1951: Background detail

March 13, 1951: What's so great about rocking?

Patty and Violet have a somewhat stereotypical conversation in a primarily verbal joke.  I like noticing what characters do during these jokes; here, it involves them picking flowers for wearing in their hair, if anything an even more stereotypically-female activity.
