Klingon (tlhIngan Hol), a language created by Dr Marc Okrand, a professional linguist, for use by the alien Klingons in some of the Star Trek movies. To make Klingon sound truly alien, Okrand used combinations of sounds which do not exist in any natural language. It is a complete language, with its own vocabulary, grammar and usage.

There is even an instute named The Klingon Language Institute that promotes and supports this language.

The fanniest thing is, I found that Google Search is available in the Klingon language.

Google's guys want to give their search service to the Alien community cause they think about the future. So when Aliens will invade our earth, google is ready !
