There warn’t anybody at the church, except maybe a hog or two, for there warn’t any lock on the door, and hogs likes a puncheon floor in summer-time because it’s cool. If you notice, most folks don’t go to church only when they’ve got to; but a hog is different.

– Mark Twain

The Adventures of Huckleberry Finn, Chapter 18. Huck says about the empty church that most people only go there when they have to. Here the author is poking fun at the hypocrisy of religious people.
