Totally serious - a little mad but interesting

A history of the gruff but surprisingly sophisticated invented language and the people who speak it.

The closest thing to 'hello' in the Klingon language is 'What do you want?' Awesome. http://bit.ly/LPtZS [from http://twitter.com/ellaminnowpea/statuses/1803100377]
