Thou hast the most unsavory similes

Falstaff
Thou hast the most unsavory similes,  and
art indeed the most comparative, rascaliest, sweet
young prince.

Before I knew thee, Hal, I knew nothing, and now
am I, if a man should speak truly, little better than
one of the wicked.

But, Hal, I prithee trouble me no
more with vanity. I would to God thou and I knew
where a commodity of good names were to be
bought. An old lord of the council rated me the
other day in the street about you, sir, but I marked
him not, and yet he talked very wisely, but I
regarded him not, and yet he talked wisely, and in
the street, too.
Prince Hal
Thou didst well, for wisdom cries out in the
streets and no man regards it.
Falstaff
O, thou hast damnable iteration, and art
indeed able to corrupt a saint. Thou hast done
much harm upon me, Hal, God forgive thee for it.
Before I knew thee, Hal, I knew nothing, and now
am I, if a man should speak truly, little better than
one of the wicked. I must give over this life, and I
will give it over. By the Lord, an I do not, I am a
villain. I'll be damned for never a king's son in
Christendom.
