The suggestion with Sam is an interesting one. He does seem to be takeing a fairly unilateral approach to dating, with Ellen at least, so mixing that up might help. At the same time, his reading of what she (and Dad) want is by and large correct. If Ellen tried to renegotiate the terms with him directly, it would be an even more important change for her than it would be for him. She did mention a chemical attraction to him, so maybe that will provide the motivation?
UPDATE: Alice and Susie chime delightfully in. The issue is that these are both historic Sunshine Girl names as well as straight-faced Corporette commenter names. Anyone want to take responsibility as the real or fake voices here?
