One day Simba decided to pull Timon off his Kiara watch and put him
on hyena watch duty. I havn't  seen a hyena in the Pridelands for the
last four years Timon thought. Are they extinct? Then an idea occured to
Timon how he could have some "fun" with his new job.
  Timon would cry "Hyena! Hyena in the Pridelands!" First it brought
Sichi the leopard. Next came Sarafina. Then Rindomo Cheetah. They were
not verry pleased with Timon's idea of "fun". "Simba," Sarafina said,
"You have to straighten your friend out - I will not listen to his cries
again." "Yeah, If this continues someone might hurt Timon," Rindomo
added.
  This conversation troubled Simba. He went to Zazu to seek advice.
During their talk Simba suddenly crouched. An object flew over both of
their heads. Zazu and Simba went over to see what it was. "Simba, it's a
brick!" Zazu's beak pulled on a string that was tied around the brick. A
piece of paper that was attached to the brick by the string unfolded.
"Simba," Zazu said, "I believe this is a suggestion to your problem with
Timon."
  Timon was asleep on his job again. He was aroused from his slumber by
the sensation of something sniffing him. When he opened his eyes Timon
saw a "Hyena! Hyena in the Pridelands!" This time no one came. Next, the
creature started licking Timon. Now, Timon thought, the hyena is tasting
me. Finally, Simba came.
"Simba," Timon cried, "save me from the hyena." "Timon," Simba replied,
"he probably smells the termites on your breath. This is not a hyena but
an aardwolf - a creature with weak jaws that eats mostly termites and
insect larva." Hearing this news Timon calmed down.
"Timon, as your punishment you will share your private termite mound
with this aardwolf." "Ah, do I have to Simba," Timon asked. "Yes," Simba
unsheathed the claws on his right paw, "or I could take the termites
from your stomach now!" "Alright, Simba I'll share - and I promise never
to cry falsely again!"

Moral : One should always tell the truth.
If you lie they won't believe you when you are telling the truth.
