A mother and a baby camel were talking one day when the baby camel asked, "Mom, why do we have these huge three-toed feet?"
The mother replied, "Well son, when we trek across the desert, our toes will help us stay on top of the soft sand."
Two minutes later the young camel asked, "Mom, why do we have these long eyelashes?"
They are there to keep the sand out of our eyes on the trips through the desert," the mother said.
"Mom, why have we got these great big humps on our back?"
"They are there to help us store water for our long treks across the desert, so we can go without drinking for long periods of time."
"So we have huge feet to stop us from sinking, long eyelashes to keep the sand out of our eyes, and these humps to store water."
"Yes dear," said the mother.
"So why are we in the San Diego Zoo?"
