I think that the two concepts have about equal
credence too. 
Big purple dinosaur that sings
and dances...
Kasumi with an axe killing people...
Nope, nobody would ever think it worth
thinking about. (Is that an oxymoron?)

I'd be just as likely to take a shovel to
either one. Why? Because the very concepts
are so ridiculous that should I ever encounter
one, I can slaughter indiscriminitely because
I'm obviously having a dream.
