HER NAME WAS DELORES. Stop there. It's senseless to supposition this to death. If it wasn't quite clear to you by Jerry's reaction and tone of voice that he remembered her name after she left, then give up already.
DELORES RHYMES WITH CLITORIS. No matter how anyone else pronounces it, the writers obviously pronounce the them (di - lor' - is) and (cli - tor' - is).
There are so many other things to talk about; don't get bogged down with one word of one episode. I hope that not having new episodes will not cause this ng to regress to that level.
Please, please . . . move on.
