A New York cab had a flat tire. The passenger suggested that the cabbie put the spare tire on. The cabbie protested with a thick Pakistani accent, "I cannot. My training for this job was that I cannot drive anywhere without an inflated spare tire in the trunk. And if I change the tire I will not have an inflated spare in the trunk."
