Kili: [Kili is gently flirting with an Elf maid when he catches Dwalin glaring at him] I can't say I fancy Elves myself, too thin. They're all high cheekbones and creamy skin. Not enough facial hair for me.
[He motions to an Elf walking behind him]
Kili: Although, that one there's not bad.
Dwalin: That's not an Elf Maid.
[the Elf turns around, revealing that he is indeed a male]
Kili: [the Dwarves burst out laughing at Kili's "mistake"] That's funny.
