leave a comment for a chance to win this drawing

brains on paper, a photo by Ape Lad on Flickr.

Here's the drawing that became this derby entry.
If you'd like a chance of winning it all for yourself, simply comment on this post.
But wait! A few things to consider:
Voting for the design on shirt.woot isn't a requirement for winning. That wouldn't be fair, plus how would I even know?
You don't have to be a fan of zombies to comment or win. That wouldn't be fair either.
Comments are still being moderated here to keep away the pharmacy spammers. I'll moderate and post them as time allows.
Be sure your email is in the appropriate box before you comment, not in the comment itself. The pharmacy spammers don't need more fodder.
The winner will be determined by an online random number generator in one week.
I may do this more often, depending on how this goes. I've got all these drawings just sitting around, when they could be hanging on your refrigerators!
The image is about ten inches wide by eight inches tall, ink on bristol paper. Nothing fancy. Also I'll be sure to sign it before I send it.
Thanks!
