No one Believes a lie

Once upon a time, a playful boy lived in a village at the foot of a hill. He had an idea one day to have fun of his fellow villagers.

He yelled at the top of his lungs, standing on a high rock, "Lion, lion, lion! Please come and save me." When the villagers heard the yell, they rushed to his aid. But when they arrived, there was no lion to be seen, and the boy was fine.

"No Lion; I did it just for fun," the boy said to the villagers. The villagers became annoyed and returned with a vengeance.

A few days later, the boy repeated the entire performance. Again, the villagers came to his aid, only to be tricked. They decided not to be tricked by him any longer. 

Unfortunately, the lion did appear one day. "Lion! Lion!" yelled the boy as loudly as he could. But no one came to his aid. 

The lion attacked the boy. The boy fought hard to save himself, but the beast killed him within minutes. As a result, once a liar, always a liar.
