What really gets me is this a milk bath.
The story is, during shooting of the milkbath scene, Nana was wearing some flesh colored modesty pasties. Just before camera rolled, someone put orange oil into the bath to make it smell better without telling anyone. Nana asked her makeup artist, "How do you get these pasties off?" Answer, "Use orange oil." When Nana got out of the tub after the scene, the pasties fell off. They never found out who did it.
