Q: where was the toothbrush invented?
A: not really sure. But it had to be Arkansas. If it were any place else, it would be called a toothbrush. 🙃
Do you mean it would be called a teethbrush?
Teeth brush? I still have all my teeth, but I was born on the High Plains and drank well water from the Ogallala Aquifer.
Now I think of it, everyone in that area had great teeth!
