THE DARK KNIGHT teaser is gone!

And so is http://www.whysoserious.com.
In its place? Well, you can still get pics of the folks who participated in the ComiCon festivities (shame on Collider for thinking there were none -- do they even pay attention?) via whysoserious' brand-new redirect: http://www.rent-a-clown.com/.
As for the teaser...well, it's still out there. You just have to get creative (potentially copyright infringing) in looking for it.
