gross fact~

There are tiny little creatures called threadworms (or pinworms) that infect about 20% of children and crawl out of their buttholes at night.


This is their life cycle:

1. You swallow a pinworm egg.

2. The pinworm hatches and chills out in your intenstines.

3. The female pinworm exits your anus while you sleep.

4. And lays eggs around your anus.

5. This kind of itches.

6. So you scratch your butt, naturally.

7. Eventually after you do that, you're likely to touch your mouth, getting the eggs back into your digestive tract.

8. The circle of life continues, forever.
