 When Myra (Clarke, Mae (qv)) is reading from the California travel  brochure, she gets a worried look on her face when she reads  "Grapefruit." This is a reference to _Public Enemy, The (1931)_ (qv)  (which also stars Cagney, James (qv) and Clarke) where Cagneys  character pushes a grapefruit into the face of hers.
