From whence this quote?
I've run across the following quote a couple of times quite recently; up until recently, I had thought it was from a friend's RPG and was said by a character in that RPG. However, it's turned up enough places that it MUST have come originally from some wider source (or else my friend's had a lot more influence in more places than I would have guessed).
The context: The speaker is talking to some aliens, who I believe were trying to threaten/frighten him:
"...We release TOXINS into our air and water to weed out the weak! We detonate ATOMIC WEAPONS in our ONLY biosphere! We NAILED our GOD to a TREE! Do not F**K with the Human Race!"
I've heard this said with a German accent; I've seen it attributed to an (apparently Russian) general "Nikolai Nikolai".
Any definitive source for this quote?
