Hamlet, Prince of Denmark

King. Where is Polonius?
Ham. In heaven. Send thither to see. If your messenger find him
not
there, seek him i' th' other place yourself. But indeed, if
you
find him not within this month, you shall nose him as you go
up
the stair, into the lobby.

King. [rises] My words fly up, my thoughts remain below.
Words without thoughts never to heaven go.

To sleep- perchance to dream: ay, there's the rub!
