FOOL: I can tell why a snail has a house.
LEAR: Why?
FOOL: Why, to put ‘s head in, not to give it away to his daughters and leave his horns without a case.

– William Shakespeare

King Lear, Act 1, Scene 5. The Fool makes a joke to Lear about his foolish decision to give his kingdom away to his daughters. He compares Lear to a snail who has given away his shell and is without a home. This passage is foreshadowing of Lear’s homelessness, which he fails to foresee despite the warnings given to him by his wise Fool.
