Sam:  Did you know that there are people who think that the Earth is flat?

Scot:  Yes.

Sam:  They believe that because their ancestors believed that.  They are not very smart.

Katie:  They are not very numerous either.

Sam:  They are called Flat Earthers.

Scot:  Yes, I have heard of Flat Earthers.  There will always be stupid people on this Planet and there is nothing we can do about it.

Sam:  But they just believe that because that is what their ancestors believed.

Katie (singing):  Tradition!

Scot:  That is exactly what I was thinking!
