Come, shelter, shelter: I have removed Falstaff’s horse, and he frets like a gummed velvet.
Come, hide, hide: I’ve moved Falstaff’s horse, and he’s getting all worked up like a sticky velvet.
Gadshill · Act 2, Scene 2
Poins moves the robbery plan forward by hiding Falstaff's horse so he'll be too exhausted to resist the scheme. The line is effective because it captures the scheming tone of the play—characters constantly plotting against each other, even in friendship. Hal and Poins are already planning to rob the robbers, showing that deception is the currency of the court.
She will, she will; justice hath liquored her. We steal as in a castle, cocksure; we have the receipt of fern-seed, we walk invisible.
It will, it will; justice has drunk it down. We steal like we’re in a fortress, totally sure of ourselves; we have the secret of fern-seed, we walk unseen.
Gadshill · Act 2, Scene 1
Gadshill boasts that the commonwealth has been corrupted so thoroughly that thieves can steal as safely as if they were in a fortress. The language is swagger—he claims to have fern-seed that makes him invisible—but the bravado rests on a real observation about power. When everyone profits from corruption, the entire apparatus becomes complicit in crime.
What, the commonwealth their boots? will she hold out water in foul way?
What, the state is their doormat? Will it hold out water in a dirty way?
Gadshill · Act 2, Scene 1
The chamberlain questions Gadshill's claim that the commonwealth is so corrupted it will support their theft. The question sticks because it is practical and skeptical—will the state really hold up under this weight of corruption, or will it leak. The chamberlain sees what Gadshill wants to deny: that corruption has limits.
