Danse macabre (...or you also have a skull in your head!)

HAMLET
That skull had a tongue in it, and could sing once:
how the knave jowls it to the ground, as if it were
Cain's jaw-bone, that did the first murder! It
might be the pate of a politician, which this ass
now o'er-reaches; one that would circumvent God,
might it not?

HORATIO
It might, my lord.

HAMLET
Or of a courtier; which could say 'Good morrow,
sweet lord! How dost thou, good lord?' This might
be my lord such-a-one, that praised my lord
such-a-one's horse, when he meant to beg it; might it not?

HORATIO
Ay, my lord.

HAMLET
Why, e'en so: and now my Lady Worm's; chapless, and
knocked about the mazzard with a sexton's spade:
here's fine revolution, an we had the trick to
see't. Did these bones cost no more the breeding,
but to play at loggats with 'em? mine ache to think on't.

First Clown
[Sings]
A pick-axe, and a spade, a spade,
For and a shrouding sheet:
O, a pit of clay for to be made
For such a guest is meet.

Throws up another skull

HAMLET
There's another: why may not that be the skull of a
lawyer? Where be his quiddities now, his quillets,
his cases, his tenures, and his tricks? why does he
suffer this rude knave now to knock him about the
sconce with a dirty shovel, and will not tell him of
his action of battery? Hum! This fellow might be
in's time a great buyer of land, with his statutes,
his recognizances, his fines, his double vouchers,
his recoveries: is this the fine of his fines, and
the recovery of his recoveries, to have his fine
pate full of fine dirt? will his vouchers vouch him
no more of his purchases, and double ones too, than
the length and breadth of a pair of indentures? The
very conveyances of his lands will hardly lie in
this box; and must the inheritor himself have no more, ha?

HORATIO
Not a jot more, my lord.

HAMLET
Is not parchment made of sheepskins?

HORATIO
Ay, my lord, and of calf-skins too.

HAMLET
They are sheep and calves which seek out assurance
in that. I will speak to this fellow. Whose
grave's this, sirrah?

First Clown
Mine, sir.

Sings

O, a pit of clay for to be made
For such a guest is meet.

HAMLET
I think it be thine, indeed; for thou liest in't.

First Clown
You lie out on't, sir, and therefore it is not
yours: for my part, I do not lie in't, and yet it is mine.

HAMLET
'Thou dost lie in't, to be in't and say it is thine:
'tis for the dead, not for the quick; therefore thou liest.
