The Camel question:
 
 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 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 stop us sinking, and
 long eyelashes to keep the sand from our eyes and these humps to
 store water, but... Mom?"
 
 "Yes son?"
 
 "Why the heck are we in the San Diego zoo?"
