...Boy, there's so many jokes to make about that. But I'll just leave it at not only is he preserving HIS sanity... I totally read it as "He's doing it to preserve my sanity?? Thanks, Rob!!"
I love that he basically just ragequit DC comics.
But for me, the best part of this story, is that he broke the news to the public by Tweeting it. From Expendables 2. I hope it was before or after the movie, because if he decided to do it during the movie...that is like, added dickishness. ;)
