Lmao, I think we've had one going on for like months now. I think it was started by Spider, so that may give you an idea of just how old it is. I'm pretty sure when he vanished off the face of AO the whole contest was like forgotten and never really finished.
Yep, I was right, here is the link, and my god, it has been going on for more than half a year:
AO Mascot contest!
I don't think I even WANT to know how many entries we have by now.
