This article doesn't appear to be notable. Very few Google hits, and no article on any other projects. Since the quote is sourced and translated, I think it should (maybe) be added to Anonymous. TheAEtalk 18:58, 15 February 2009 (UTC)
Weak keep. Here are three more sources not only for the notability of Mary Hirsch, but also for this quote itself. But, I don't know how much notability a person or quote needs. Maybe someone who knows more about the English Wikiquote policies can say something. Maybe it can be joined onto another page, about "Comedy" or "Humour" or "Writers" or something.
