Logic

An Arab Muslim enters a taxi in New York City. Once he is seated he demands the cab driver turn off the radio because, as decreed by his religion, he must not hear music. He goes on that in the time of the prophet there was no music, especially Western music (which is music of the infidels). (And, there certainly was no radio.)

The cab driver switches off the radio, stops the cab and opens the back door.

The Muslim asks him:

"What are you doing, man?"

The cabby answers:

"In the time of the prophet there were no taxis. Get your ass out and wait for a camel."
