A domesticated duck stood on the edge of a cliff and thought to himself, "If a swan can fly, I can too. After all we are all the same". He then took off by jumping off the cliff and fell to the ground.
A vulture, having witnessed the whole event came by while the duck was still breathing and said, "Stupidity is trying to be something you are not."
He then tore off the duck flesh and ate heartily.
