Yetta's Birthday

Pete and Sally's freind Jim from New York visits. Yetta's behaving herself as instructed, but then she doesn't need to do much as Sally has strangely started behaving just like her, insisting everyone eat, interogating Jim and saying 'Oy Vay' a lot. Is it a bad case of Stolkholm Syndrome or is Sally hiding something? And does Jim have the 'key', to finding Carole (with an e)? Meanwhile Tammy's love life is just like, you know, over, and Yetta's the only one that seems to care, if only she could hear her.
