> The man from Glasgow then bellowed back...

Three philosophers are riding the train to Edinburgh for a scholarly
conference. They see a black sheep in a pasture.

"Interesting: the sheep in Scotland are black."

"No... there exists at least one black sheep in Scotland."

"No... There exists at least one sheep, *one side of which is black*, in
Scotland."
