Teenage Mutant Ninja Turtles

(An extract from the book 'The Good Psychologist' by Noam Shpancer

A story about an ancient ruler who summoned his wisest adviser and asked him, what does the World stand on?
The World, said the wise man, stands on the back of an Elephant.
What does the Elephant stand on? asked the ruler.
The Elephant, it is known, stands on the back of a Turtle.
What does the Turtle stand on?
The wise man tugged at his beard: The Turtle stands on the back of another Turtle. And what does this turtle stand on?
Another Turtle.
And that one?
The wise man threw his hands up in desperation: I promise you, sir, it's Turtles all the way down.
