I found this old Sunday Comics MOTU strip on Flickr, and it mentions that you can enter to win a role in a DC Comic Book. "Grand Prize winner will actually be written and drawn into the story."

Does anyone know anything about this? It's been awhile since I've read the DC Comics, so it's possible I'm forgetting/missing something.
