Dirty water is what makes the
world go 'round.
Think about it.
We all drink water. 'Course, it isn't really pure water. It's dirty water. Some places have dirtier water than others.
And our blood is made up of dirty water. Filthy water, really. It's all rusty (being full of iron), and it has icky proteins in it.
Our bodies are made of water, too. They are made of putrid water. Water that has gotten so icky and nasty that it has solidified, grown hair, and started walking around.
Now that is dirty water.
And don't forget this: When you mix acids and bases, you get dirty water. (It's salty)
Dirty water makes the world go 'round.
