Books by Tolstoy. I think that relatively few people really have read "War and Peace" or "Anna Karenina" from beginning to end, although in their defense I have to say that the latter is mostly boring after the death of Anna. For good measure, though, throw in a copy of Tolstoy's "The Cossacks," which I actually read in Russian many years ago.
There was a cartoon in The New Yorker many years ago that showed the counter of a diner (a type of low-cost eatery in the United States) and a waitress calling into the kitchen "Have we got any strawberries crushed in cream cheese?" At the far end of the counter is Proust, in the well known pose with one hand under his chin.
I asked a friend who had read "Remembrance of Things Past" what the reference was, and he said he didn't know. He said that he had only read the first volume, "Swann's Way." That prompted me to read the entire work. I did find that reference to strawberries crushed in cream cheese, though, fairly early on in "Swann's Way," so my friend probably hadn't even read one volume. Send him one of those crates of books.
