Camels

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."

"OK," said the son. A few minutes later the son asks, "Mom,
why have I got these great long eyelashes?"

"They are there to keep the sand out of your eyes on the
trips through the desert."

"Thanks, Mom," replies the son. After a short while, the son
returns and asks, "Mom, why have I got these great big humps
on my back?"

The mother, now a little impatient with the boy, replies,
"They are there to help us store fat for our long treks
across the desert, so we can go without water for long
periods."

"That's great, Mom. So we have huge feet to stop us sinking,
and long eyelashes to keep the sand from our eyes, and these
humps to store water, but Mom..."

"Yes, son?"

"Why are we in the San Diego zoo?"
