Because it is not called a teethbrush.
Drones can't tell either
Go visit his family tree.
A toothbrush.
When your toothbrush stops working mid brushing
If it where anyone else it woulda been called a teethbrush
Cause if it was invented anywhere else it'd be called a teethbrush.
So accountants could have someone to laugh at.
