Sounds like a reasonable question to me....
Got this in an email........
A young Arab asks his father, "What is that weird hat you are wearing?"
The father said, "Why, it's a 'chechia', because in the desert it protects our heads from the sun."
"And what is this type of weird clothing that you are wearing?" asked the young man.
"It's a 'djbellah', because in the desert it is very hot and it protects your body." said the father.
The son asked, "And what about these ugly shoes on your feet?
His father replied, "These are 'babouches', which keep us from burning our feet when in the desert."
"Tell me, Abba?" added the boy.
"Yes, my son?"
"Why are we living in Toms River, New Jersey and you're still wearing all this sh!t?"
