LEAR.
Go you before to Gloucester with these letters: acquaint my daughter no further with anything you know than comes from her demand out of the letter. If your diligence be not speedy, I shall be there afore you.

KENT.
I will not sleep, my lord, till I have delivered your letter.

[Exit.]

FOOL.
If a man’s brains were in’s heels, were’t not in danger of kibes?

LEAR.
Ay, boy.

FOOL.
Then I prithee be merry; thy wit shall not go slipshod.

LEAR.
Ha, ha, ha!

FOOL.
Shalt see thy other daughter will use thee kindly, for though she’s as like this as a crab’s like an apple, yet I can tell what I can tell.

LEAR.
What canst tell, boy?

FOOL.
She’ll taste as like this as a crab does to a crab. Thou canst tell why one’s nose stands i’the middle on’s face?
