Pandorica

There had to have been a first time. A time when the Doctor didn't get it exactly right. Something sparked the paradoxes that are strewn across his timeline.

[Doctor Who - Rights to the BBC and blah blah - This is just something that I had kicking around in my head while Chameleon Circuit's Big Bang Two played in my brain for two days straight]

I've decided I like paradoxes. I'll add some more as my mind thinks up stuff. Feel free to suggest.
