What's the last line of Hamlet? You decide.
Dialogue from Act 5 Scene 2 seems to clinch it:
Hamlet: I cannot live to hear the news from England;
But I do prophesy the election lights
On Fortinbras: he has my dying voice;
So tell him, with the occurrents, more and less,
Which have solicited. The rest is silence. (Hamlet dies)
Of course, this closes the play:
Prince Fortinbras: Take up the bodies: such a sight as this
Becomes the field, but here shows much amiss.
Go, bid the soldiers shoot.
