They say a wall is medieval, well so is a wheel. A wheel is older than a wall. And I looked at every single car out there, even the really expensive ones the secret service use.

Donald Trump, 45th President of the United States of America
I'm pretty sure I know about this, but was the wall invented before, or after the wheel?
