I think my favorite would have to be the one by Rudyard Kipling
When the Man waked up he said,
"What is the Wild Dog doing here?"
And the Woman said,
"His name is not Wild Dog any more,
but the First Friend,
because he will be our friend
for always and always and always."
I thought that was a pretty good summary of a hundred thousand years of history - or fifteen thousand, depending on which archaeological study you believe.
And...I just noticed it is Rudyard Kipling's birthday today!
