Just about all of your major religions foretell some sort of end times scenario, usually involving plagues, famine, earthquakes, rivers running red with blood - that sort of thing.
It's all very scary stuff, but we think they might have left out one equally surefire sign of the Apocalypse:
Yes, that's Justin Bieber hanging out with Marilyn Manson at a club in LA on the left, and Manson posing for a selfie in a Bieber t-shirt on the right.
We don't know if these two are friends now or what, but this is a seriously unexpected pairing, and not only because we didn't think the planet could handle this much D-baggery in one place.
Like millions of others, Manson has reveled in mocking Bieber online on several occasions.
It seems he particularly took exception to Bieber's habit of rocking Manson t-shirts at unusual times like...at church (seriously).
So it's more than a little surprising that Marilyn and the Biebs have found some common ground.
Of course, Manson has demonstrated a willingness to bury the hatchet with famous youngsters in the past, such as when he dedicated a song to Paris Jackson after publicly poking fun at her dad.
We're not saying it isn't weird, but we'd much rather see Justin posing for a selfie with a 47-year-old goth than using his Instagram to try and win Selena Gomez back.
Both situations are creepy, but at least this way no one innocent gets hurt.
