A Mathematician, an engineer and a physicist were traveling through Scotland when they saw a black sheep through the window of the train.

“Aha”, says the engineer, “I see that Scottish sheep are black.”

“Hmm”, says the physicist, “You mean that some Scottish sheep are black”.

“No”, says the mathematician, “All we know is that there is at least one sheep in Scotland, and that at least one side of that one sheep is black!”
