Proving once again that we live in a fascinating world full of nearly infinite possibilities, here is a photograph of Michael Douglas, the Oscar-winning star of the 1987 classic "Wall Street," fist-bumping Marvel superhero Ant-Man inside the New York Stock Exchange building earlier today.

Of course, it was promotion for Marvel Studios' "Ant-Man," opening this Friday, with Douglas ringing the NYSE Closing Bell. In the film, Michael Douglas plays long-running Marvel character Hank Pym, the original Ant-Man of comic book lore. Paul Rudd stars as Scott Lang, Marvel Comics' subsequent Ant-Man -- though unfortunately, it likely wasn't Rudd inside the costume at the NYSE; perhaps the one thing that could make that photo even more improbable. Fingers crossed that in 2016, we'll get Doctor Strange high-fiving Tilda Swinton inside the United Nations Headquarters.
