Question: Tell us another joke

Anne Green answered on 7 Nov 2018:

I’m not very good at telling jokes. Here’s a very geeky one:

An engineer, a physicist, and a mathematician were on a train heading north, and had just crossed the border into Scotland.

The engineer looked out of the window and said “Look! Scottish sheep are black!”
The physicist said, “No, no. Some Scottish sheep are black.”
The mathematician looked irritated. “There is at least one field, containing at least one sheep, of which at least one side is black.”
