The Missing Goat :

It all started one lazy Sunday afternoon in a small town near Toronto in Canada.
Two school-going friends had a crazy idea.
They rounded up three goats from the neighborhood and painted the number 1, 2 and 4 on their sides.
That night they let the goats loose inside their school building.
The next morning, when the authorities entered the school, they could smell something was wrong.
They soon saw goat droppings on the stairs and near the entrance and realized that some goats had entered the building.
A search was immediately launched and very soon, the three goats were found.
But the authorities were worried, where was goat No. 3?
They spent the rest of the day looking for goat No.3.
Gradually there was panic and frustration.
