"The quote was plagarized from Genghis Khan"

Goldberg notes it was plagiarized, although not the source. I would be interested to see where you found that quote; I find the prospect of Genghis using words like "bedewed", or, for that matter, compound sentences, pretty humourous. It just smacks of historical embellishment.

The source of the quote:

I've seen various iterations of the original quote, all quite different.

This is another version of Khan's quote, with words that seem more Khan-appropriate. Source is Keegan's book, which is well worth reading:

In "A History of Warfare," John Keegan describes the curious mentality and values of a warrior. Genghis Khan, for example, "questioning his Mongol comrades-in-arms about life's sweetest pleasure and being told it lay in falconry, replied:

'You are mistaken. Man's greatest good fortune is to chase and defeat his enemy, seize his total possessions, leave his married women weeping and wailing, ride his gelding [and] use the bodies of his women as a nightshirt and support.'"

Al Gore invented it and first used it in Love Story on the Internet.
