The three cats and the snake.

Once upon a time some little cats wanted to build a house to protect themselves, one made one of straw, another one made it of wood and the other made it of brick.

That with the straw house ended soon, then the one with the wooden house and finally that with the brick house.

Then they all settled down, but the one in the brick house had little left.

Then the snake came and told them 'I will blow and blow and your house will fall down'. That with the straw house did not believe him and he knocked it down.

He went to the wooden house and also knocked it down. They went to the brick house, that of the smartest cat and the snake could not knock it down and left.
