Now that I've watched TONS of ridiculous old movies, I'm not quite as fond of Pillow Talk's absurdity as I originally was, but it's still pretty classic.
And - like Sex and the Single Girl - it's one of the major plot sources for the movie Down with Love.
Starring Doris Day, Rock Hudson and Tony Randall.

Doris is so horrified by this. As though nothing illicit could happen on a couch without a fold-out bed.
This must have been such a fun set to design and decorate.
