I had a similar dream about 2 months ago. Somebody was 'roleplaying' as Cracky on .71 and everybody else was playing along, knowing that it couldn't possibly be her. It went on like that for about 20 posts in a single thread, then suddenly the roleplayer posted a massive amount of Cracky pics that weren't even in the thumbnail-rare list and it was understood that it actually was Cracky.
This reminds me, it has been quite a while since a rare was posted.
