three scientists were traveling through scotland by train.  they were an
astronomer, a physicist and a mathematician [it's a good thing the astronomy
and physics departments here aren't on the net!].  they were watching the
scenery out the window when they saw a lone black sheep on a hillside.

"look!" said the astronomer, "the sheep in scotland are black."

"no," replied the physicist, "you can only say that some of the sheep in 
scotland are black".

after a while the mathematician spoke up.  "actually, all we know is that at
least one sheep in scotland is black, on at least one side".
