The Constable of France.
-Montjoy
Montjoy is a herald sent to talk to Henry and with today's line he is answering Henry's question "Who sent thee?' This is right before the battle of Angincourt in which, as you know if you've read any of these posts, the outnumbered English destroy the French. Montjoy has come to see if Henry is interested in surrendering since he's so outnumbered. Henry's reply? 'Don't count your chickens before they're hatched, buddy. Get lost!'
Well, that's a bit of paraphrasing. His actual reply (or part of it);
The man that once did sell the lion's skin
While the beast lived, was killed with hunting him.
That's much better than the chicken saying, don't you think?
So today you got two lines for the price of one. No extra charge.
That's a good looking Lion! It's from Nina's box of figurines and I think it's Simba. Needless to say, I won't be selling his skin.
