In ACT I, SCENE II of HENRY V, Shakespeare writes the following dialogue:

FIRST AMBASSADOR: He therefore sends you, meeter for your spirit,

This tun of treasure; and, in lieu of this,

Desires you let the dukedoms that you claim

Hear no more of you. This the Dauphin speaks.

KING HENRY V: What treasure, uncle?

EXETER: Tennis-balls, my liege.
