You try to do what Legolas did in TTT (sliding down the stairs on a shield or maybe in your case, a sled of some sort)
You carry bow and arrows, an ax or a sword with you at all time
You know you're obsessed when on of your friend is being insulted and you defend him by saying "He is Aragorn, son of Arathorn and you owe him your allegiance." or threaten him with your weapon.
You have competitions with your friends over how many orcs you've killed.
You try to swing onto a horse while it's running (Legolas thing again!)
