Don't. Just don't. I know you want to, and I do, too. But it's just too easy. Don't give in. I know it isn't easy. It feels like you're being drawn inexorably into some sort of cum-spurting black hole or something. But don't make the joke. The joke is too easy.

Lungs evolved from the digestive tract as it's more efficient to just have a separate organ for it, which is also the reason you can shoot oxygen up your butthole to breathe

So maybe this discovery will have some alternative usefulness
