I wonder.... If the black box flight recorder is never damaged during a plane crash, why isn't the whole airplane made out of the same stuff? Why is there an expiration date on sour cream? If most car accidents occur within five miles of home, why doesn't everyone just move 10 miles away? If man evolved from monkeys and apes, why do we still have monkeys and apes? I went to a bookstore and asked the saleswoman, "Where's the self-help section?" She said if she told me, it would defeat the purpose. If all those psychics know the winning lottery numbers, why are they all still working? Why do we say something is out of whack? What is a whack? Do infants enjoy infancy as much as adults enjoy adultery? If a pig loses its voice, is it disgruntled? Why do women wear evening gowns to nightclubs? Shouldn't they be wearing night gowns?
