From this article:
Said Obama: "Contrary to the rumors you have heard, I was not born in a manger. I was actually born on Krypton and sent here by my father, Jor-el, to save the planet Earth," a reference to Superman.
Really, it's like McCain hasn't even been trying to appeal to me as a geek. Where's invocation of The Force? His reference to his Spidey Sense? Oh, wait...
I believe McCain served on the USS Enterprise.
Well played, sir. Well played.
