A Connecticut Yankee in King Arthur's Court, Part 3.
Pretty soon, various kinds of bugs and ants and worms and things began to flock in out of the wet and crawl down inside my armor to get warm; and while some of them behaved well enough, and snuggled up amongst my clothes and got quiet, the majority were of a restless, uncomfortable sort, and never stayed still, but went on prowling and hunting for they did not know what; especially the ants, which went tickling along in wearisome procession from one end of me to the other by the hour, and are a kind of creatures which I never wish to sleep with again.
