I chose Ed and Roy. They remind me of those little kids who say they hate each other and swear they will defeat the other one day in a Pokemon battle, or some other game. But beyond all that, they're really just best friends.
Boys will be boys. How sweet...
Ed: What're you calling sweet? Me and that stuck-up pig? Friends? *snorts in laughter* We're rivals to the end.
Roy: Well if I'm a stuck-up pig, then you're a shorty.
Ed: Who're you calling so short that he can't be seen even under a microscope?
Roy: What's that buzzing I hear? Sounds like an insect, but I can't see anything. Hmm... Maybe because it's too SMALL. *evil grin*
Ed: Why you... Obnoxious ass!
Are they supposed to be soldiers? Sheesh!
