The entire script of VALLEY OF THE DOLLS is quotable. However, one exchange will do.
Helen Lawson: Look, they drummed you out of Hollywood, so you come crawling back to Broadway. Well, Broadway doesn't go for booze and dope. Now get out of my way 'cause I've got a man waitin' for me.
Neely O'Hara: That's a change from the fags you're usually with.
Helen: At least I never married one.
and, of course, it goes on from there right to the infamous wig-pulling/flushing scene.
