Shakespeare Refences in The Devil Wears Prada

Lauren Weisberger's novel The Devil Wears Prada contains a couple of Shakespeare references. The first is a Macbeth reference, with Weisberger writing, "Within twenty-four hours of being 'put on notice' that I would be needing some makeup and more than a few tips, she had created the Be-All, End-All Cosmetic Catchall" (p. 292). The phrase "be-all, end-all" comes from Macbeth, when Macbeth says, "If th' assassination/Could trammel up the consequence and catch/With his surcease success, that but this blow/Might be the be-all and end-all here." The other reference is to the sonnets. Weisberger writes, "Isaac sneezed a very cute baby sneeze in response, and Jill looked as though he'd just risen up from her arms a full-grown man and recited a few Shakespearean sonnets" (p. 345). This book was published in 2003. The copy I read was a hardcover edition that was originally a library book.
