In other vein, it is hilarious that Twain drew a lot of criticism for Huck Finn from two directions. The first was his attack on racism - this is the contemporary criticism that modern critics usually discuss in retrospect. HOWEVER, Twain also drew a great deal of criticism from the drawing room crowd for vulgarity and crassness.

I don't remember Twains' quote, but after some blistering reviews condemning the vulgarity in the book, Twain crowed that they had just sold a buttload more books!
