[Thor walks into "Pet Palace.".]
Thor: I need a horse!
Loki: I am now ruler of Asgard. I am... Your king.
Odin: Whosoever holds this hammer, should he be worthy, shall possess the powers of Thor.
Darcy: How can you eat ten boxes of Pop Tarts and still be this hungry?
Thor: Oh, no... This is Earth, isn't it?
Odin: I have sacrificed much to achieve peace. So too must a new generation sacrifice to maintain that peace. Responsibility! Duty! Honour! These are not mere virtues to which we must aspire! They are essential to every soldier, to every king!
Odin: Thor, Odin's Son, through your arrogance and stupidity, you have opened these peaceful realms and innocent lives to the horror and devastation of war.
Agent Phil Coulson: It's not easy to do what you did. You made my men - some of the most highly trained professionals in the world - look like a bunch of minimum-wage mall cops. In my experience, it takes someone who's received similar training to do what you did to them. Why don't you tell me where you received that training? Afghanistan, Chechnya? No, you strike me more as the soldier of fortune type. Who are you?
Thor: For the first time in my life, I have no idea what I'm supposed to do.
Darcy: You know, for a crazy homeless person... He's pretty cut.
Answer: When initially found by Odin, he does. Something then acts on him that causes him to mimic Odin's more human appearance, which he then keeps until his exposure to the frost giants during the events of the film, which tips him off to his true nature. Whether this was caused by some magic inherent in Loki even as a baby or whether Odin did something to disguise the child's true origin is unrevealed.
