[CORA, spoken]
Dr. Hapgood, I want you to meet my Town Council: Controller Schub, Treasurer Cooley, and Chief of Police Magruder. Gentlemen, this dazzling doctor is going to solve our problem, and find out which of the people on this line are sane, and which are not. 

[SCHUB, spoken]
How are you going to do it, Dr. Hapgood?

[HAPGOOD, spoken]
Well, I'm going to example them according to the principles of logic. 

[CORA, spoken]
Logic?

[HAPGOOD, spoken]
Yes. 

Grass is green
Sky is blue
False is false
And true is true
Who is who?
You are you, I'm me!
Simple? Simple? Simple?
Simple as A-B-C
Simple as one-two-three

[SCHUB, spoken]
But doctor, which on that line is what?
