A Connecticut Yankee in King Arthur's Court, Part 3.
At first I had only two hands; but before I had left home I was already employing fifteen, and running night and day; and the atmospheric result was getting so pronounced that the king went sort of fainting and gasping around and said he did not believe he could stand it much longer, and Sir Launcelot got so that he did hardly anything but walk up and down the roof and swear, although I told him it was worse up there than anywhere else, but he said he wanted plenty of air; and he was always complaining that a palace was no place for a soap factory anyway, and said if a man was to start one in his house he would be damned if he wouldn't strangle him.
