Nowadays, it gets harder and harder to tell when people are joking and when they're seriously going to do something crazy. For instance, before we enter a serious and bewildering debate with a Flat Earther, we might assume that nobody seriously believes that the Earth is flat.
But even wild ideas that start as jokes run the risk of reaching at least one person who's daring enough to actually try the ridiculous thing that people are ironically enthusiastic about.
That unfortunate reality is how we had people actually trying to eat Tide pods a couple of years ago, and it seems to be responsible for yet another dangerous challenge.
