When the phone rings, Berta (Conchata Ferrell) puts the sandwich in her mouth. In the next scene, when she is talking to Charlie, the sandwich is missing. In the very next scene it is again in her hand.
When Rose is talking with Charlie on the balcony, she references the German word Schadenfreude with respect to her taking joy in his misery. The German pronunciation of this word is, phonetically, SHA-DEN-FROY-DUH, whereas Rose pronounces it SHA-DEN-FROYD.
