I don't know who said it, but I heard this joke mentioned yesterday:

Microplastics are everywhere, even in our bodies. There's microplastics in your blood, in your lungs, in your brain, even in your cum. It doesn't matter if you're young or old or rich or poor. Even billionairs have microplastics in their cum. And microplastics in billionaire's cum is something we should be concerned about, because children eat that.
