If you’ve heard of the “Bird Box Challenge,” where people blindfold themselves (and sometimes their children) doing different and sometimes dangerous activities in order to mimic characters in Netflix’s “Bird Box” film, perhaps you also heard that Netflix took to Twitter to warn against taking this challenge.

As the online streaming service put it: “Can’t believe I have to say this, but: PLEASE DO NOT HURT YOURSELVES WITH THIS BIRD BOX CHALLENGE. We don’t know how this started, and we appreciate the love, but Boy and Girl have just one wish for 2019 and it is that you not end up in the hospital due to memes.”
