Guy sitting on brown horse: "You promise you won't shoot Elrond this time, okay, Leggy?"
Legolas: *sighs* "...Okay, okay, I promise." *evil grin when no one's looking* *starts talking to himself* "I shot my arrow into the air, it fell to Earth, I know not where..." *imagines Elrond getting shot* "Um...oops. HEE HEE HEE HEE!!"

Only Howling Shadow Wolf and maybe a select few people would get this joke, so if you're confused, it's okay.
