George: We can!
Mildred: We can't!!
Edit
Robin: (reading the title of Chrissy's book) 'Sex and the Single Girl'. What's that about?
Chrissy: Church architecture.

Jo: Don't talk about me as if I weren't here!
Robin: (jokingly) Where did that voice come from?
Jo: Look, I wouldn't mind if I wasn't, 'cause I wouldn't know, but I am and I do. So, don't!
Edit
Chrissy is reading 'Sex and the Single Girl', a rather controversial 1962 book by Helen Gurley Brown, which advocated a liberal lifestyle. It is ironic that Chrissy does everything she can to keep Robin out of her bedroom.
