An engineer, an experimental physicist, a theoretical physicist, and a
philosopher
were hiking through the hills of Scotland. Cresting the top of one hill,
they see,
on top of the next, a black sheep. The engineer says: "What do you know,
the sheep in Scotland are black."
"Well, *some* of the sheep in Scotland are black," replies the
experimental physicist. The theoretical physicist considers this for a
moment
and says "Well, at least one of the sheep in Scotland is black."
"Well," the philosopher responds, "on one side, anyway."
