Ever dumped someone because of their taste in books?

The New York Times Book Review has a rather interesting article up called It’s Not You, It’s Your Books, which is about maintaining a relationship with someone whose reading tastes don’t mesh with your own. I can’t say I’ve ever broken up with someone over their taste in books, but thinking about it now, I do expect my significant others to grok certain literary references (<--and that's one of them). So I must turn to our readers: are there any literary references/books you expect your potential dates to be familiar with? In other, less flippant news: Largehearted Boy has William Walsh’s music playlist for Without Wax up at its site.
