A mother and baby camel were talking one day when the baby camel asked "Mom, why do I have these huge two toed feet?"
The mother replied, "Well son, when we trek across the desert your toes will help you to stay on top of the soft sand.,"
"OK," said the son. A few minutes later the son asked "Mom, why have I got these great long eyelashes?"
"They are there to keep the sand out of your eyes on the trips throught the desert," replied the mother.
"Thanks Mom," replied the son. After a short while, the son returns and asked, "Mom, why have I got these great big humps on my back?"
The mother, now a little impatient with the young camel replied "They are there to help us store water for our long treks across the desert, so we can go without drinking for long periods."
"That's great, Mom. So we have huge feet to keep us from sinking in the sand, and great long eyelashes to keep the sand out of our eyes, and these humps to store water. But MoM..."
"Yes, son?" inquired the mother.
"Why the heck are we in the San Diego zoo?"
