Since discovering Things That Don't Exist a week or so ago I haven't been able to get some of them out of my head. So in the hope that blogging might be a weird form of exorcism, I'm going to share a few with you now. The thing that doesn't exist that has the most peculiar hold on me is The Credible Hulk, which always seems to be on the site's top 5 list.

But also noteworthy, I think are "A creature that looks like a door and sneaks into peoples houses and stands by a wall and waits for people to enter it and then digests them", the lovechild of J. Alfred Prufrock, 1:1 scale maps and Pope John Paul George Ringo.

Speaking of weird stuff, Slate's explainers are really on a roll at the moment, in recent days bringing us who decides when a celestial body is a planet, what extinct birds sound like and who gets to wake the president and why.

They don't, however, explain why you'd bother.
