Enter KING and QUEEN with ROSENCRANTZ and GUILDENSTERN.
KING: There's matter in these sighs, these profound heaves --
You must translate, 'tis fit we understand them.
Where is your son?
QUEEN: Bestow this place on us a little while.
[Exeunt Rosencrantz and Guildenstern.]
Ah, mine own lord, what have I seen to-night! 
KING: What, Gertrude? How does Hamlet?
QUEEN: Mad as the sea and wind when both contend
Which is the mightier. In his lawless fit,
Behind the arras hearing something stir,
Whips out his rapier, cries, łA rat, a rat!˛ 
And in this brainish apprehension kills
The unseen good old man.
