It is the knights who say, "NI!!!!"
Legolas: Nuuuu
Galadriel: Legolas, It's Ni!
Legolas: Does this tunic make me look fat?
Aragorn: Don't tell the Elf. I put lard in his lembas.
Boromir: *snicker*
Legolas: I am the dancing queen...
Legolas: Stupid Dwarf.
Elrond: Now be nice children. If you want to play together, you must learn how to share.
