Figwit

Bret McKenzie as "Elf Escort" in The Lord of the Rings: The Return of the King.

Figwit is a fan-created name for a then-unnamed Elf Escort in Peter Jackson's The Lord of the Rings film series, played by Bret McKenzie of the musical duo Flight of the Conchords. The name Figwit derives from an acronym for "Frodo is great...who is THAT?!?" [sic]. The character quickly and unexpectedly became popular among Tolkien fandom, and is perceived as an example of famous for being famous, a view shared by the character's actor himself.
