The winner is Becky, of Good Grief! fame. Here is a picture to prove the results:

But wait, I hear you say, doesn't that picture say 1001 comments, and the contest was for the 1000th comment? Well, my eagle eyed reader, that would be correct, however you forgot that I discounted the comment Thad made on the contest entry (sorry, Thad).
Congratulations to you, Becky! What will your prize be? Only I know for sure (and I don't have it yet, but I will soon). I will admit that I thought perhaps a Hello, Kitty calendar would be in order, but I didn't think that was 'blankbaby-ish,' so I settled on something very differnet.
