Then the old man got to cussing and cussed everything and everybody he could think of, and then cussed them all over again to make sure he hadn’t skipped any, and after that he polished off with a kind of a general cuss all round, including a considerable parcel of people which he didn’t know the names of, and so called them what’s-his-name when he got to them, and went right along with his cussing.
– Mark Twain
The Adventures of Huckleberry Finn, Chapter 6. Huck’s life with his cruel drunkard father Pap is not a barrel of laughs, more a barrel of alcohol and man’s inhumanity to man.
