Just threw this together out of Nate's source photo.
Subject: Mark holding a carp. Possibly a Holy Carp.
For some reason I can't get the html code to not chop the pic, so here is the link:
This blog is designed to create photoshopped pictures of Mark. Mark will not be informed of this website, and no one will tell him until the appointed time. Note that if you click on a photo, you can see it in fullsize.
