Well this joke went nowhere. Fair enough. I guess I should translate.
"I admit Klingon is a minor language. Why is German spoken here but Klingon isn't. Klingon is just as important as other so called languages"
well the answer is clear. I'm the only one who knows it (or at least has the resources to write it)
Edit: it's not a case of showing off. Someone started a thread in german. Now only someone who knows german could understand him. The joke is only someone who understands klingon understands this.
