In the Lord of the Rings trilogy by J.R.R. Tolkien, Nazgul are the most deadly servants that Sauron has. Despite the fact throughout the entire series the Nazgul are dreaded by everyone, the Nazgul are proven to be extremely easy to kill to the disappointment of the viewers.
Nazgul: No man cankill me.
Eowyn: I am no man *stab*
Nazgul: *shrieks and dies*
Viewer: What. The. Fuck.
The combination of two strange worlds, events and themes into one world and strange, surprising and exciting events may occur. (Hense Nazgal - LOTR, then Hoth - Starwars = would make one strange world).
Mike: Wanna make some carpets?
