Ophelia: "I do not know, my lord, what I should think."

Polonius: "Marry, I will teach teach you. Think of yourself a baby That you have ta'en these tenders for true pay, Which are not sterling. Tender yourself more dearly, Or (not to crack the wind of the poor phrase, Running it thus) you'll tender me a fool."
