 The filmmakers were nervous about showing Rocky and Ginger kissing,  fearing the sight of two chickens touching beaks would look too  awkward. This led to the running gag of their being interrupted  every time time they are about to kiss (by the sound of the pie  machine, by Ginger slapping Rocky, by the gravy explosion, etc.).  When the kiss finally comes, it is staged so that the actual contact  of "lips" is hidden.
