Ay, that incestuous, that adulterate beast,
With witchcraft of his wit, with traitorous gifts -
O wicked wit and gifts, that have the power
So to seduce! - won to his shameful lust
The will of my most seeming-virtuous queen:
O Hamlet, what a falling-off was there!
From me, whose love was of that dignity
That it went hand in hand even with the vow
I made to her in marriage, and to decline
Upon a wretch whose natural gifts were poor
To those of mine!
But virtue, as it never will be moved,
Though lewdness court it in a shape of heaven,
So lust, though to a radiant angel linked,
Will sate itself in a celestial bed,
And prey on garbage.
But, soft! methinks I scent the morning air;

As discussed back in Episode 15, incest would have been a contentious topic in Shakespeare's England - particularly when the incest instance of a man marrying his dead brother's wife. (This had happened when Henry VIII married Catherine of Aragon.)
In Shakespeare's usage, garbage had a much fouler meaning, to do with offal and entrails. It still meant worthless material, as today, but likening Claudius to such foulness is a direct attack.
