If Obama Really Has an iPad, Why Won't He Just Show Us the RECEIPT?

Is that Obama's iPad?! Look, he's made a few vague references about possibly owning an iPad (he's the president, man). And since we're making him prove the authenticity of everything right now, I WANT TO SEE A RECEIPT, DAMMIT.

Is it an iPad 1 or iPad 2?! What if it's a knockoff?! What if he bought one on the Chinese black market?! What if Jobs sent him one for FREE in exchange for FAVORS?!?!?!?!? WE NEED TO KNOW THESE THINGS. [Flickr via Slate]
