A mother and baby camel are talking one day when the baby camel asks, "Mom, why have I got these huge three-toed feet?"
The mother replies, "Well, son, when we trek across the desert, your toes will help you to stay on top of the soft sand."
A few minutes later, the young camel asks, "Mom, why have I got these long eyelashes?"
"They are there to keep the sand out of your eyes on the trips through the desert."
"Mom, why have I got these great big humps on my 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."
"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."
"So why are we in the San Diego Zoo?"
