That was the scene I'd been waiting for all season. (Wish I could say the same for the entire episode.) Don and Joan playing hooky at a bar, Rosemary Clooney (?) on the jukebox. Brilliant dialogue, beautifully acted. Oh, they must never, ever hook up. But, omigod, if they do, my head will explode and my eyes will pop out of my head. What do you think, Mad Men fans: Will they or won't they?
