I liked how you handled it...
Cool, wierd, random... but it aludes to a much larger storyline.
You did a good job in making this snapshot of a moment in some epic story... and you did the shock value moment well... you didn't just throw the elephant trunk dick in our faces... but hinted at the whole picture.
I loved the elephant, human amalgam the son becomes in the end... this would make a good preview for a really whacked out sci-fi adventure! HAHA!
