the following are quotes from mgs2, more can be found here. otacon tried motivating snake by telling him chinese proverbs, the way mei ling did back in mgs1. she even made him a cheat sheet with all the meanings, but he managed to get them all wrong anyway, he's such a dork <3

Otacon: Snake, you of course know the saying "One for all, all for one."
Snake: What is this, all of a sudden?
Otacon: Oh, I figured you'd need a lot of motivation, so I came prepared. It's from 'The Three Musketeers' -- the book, not the candy bar. Anyway, it means that if you go up against everyone by yourself, they'll gang up on you too. I think. Since you're on your own on that ship, you need to take this to heart and avoid confrontations. How was that? Just like the old days, huh?
Snake: Almost reminds me of Mei Ling, but... You sure you got it right?
Otacon: Of course! And I'll teach you a lot more of these, you can count on it.
Snake: Great...

they are all gems, really, but i just wanted some of my favorite ones to be here, so more under the cut.
