Wasn't me!

I have to wonder if they can somehow all become pregnant with a single fertilization or if someone was incredibly unlucky.

They're a hive mind, not a unified body.

Girls who spend time together have their periods synchronize.

It's a bingo

Why unlucky?
I would be so damn happy!

A myth, based on a single study in the 1970s, which has since been shown to be untrue. The original study's methodology was found to be deeply flawed, and followup studies have repeatedly failed to replicate its results.

But for some reason, people who should know better continue to uncritically accept it and present it to others as scientific fact.
