One day, shortly after the birth of their new baby, the mother had to go out to do some errands, so the proud father stayed home to watch his wonderful new son. Soon after the mother left, the baby started to cry. The father did everything he could think of, but the baby just wouldn't stop crying. Finally, the dad got so worried he decided to take the infant to the doctor. After the doctor listened to all the father had done to get the baby to stop crying, the doctor began to examine the baby's ears, chest and then down to the diaper area. When he opened the diaper, he found was indeed full. "Here's the problem," the doctor explained. "He just needs to be changed." The perplexed father remarked, "But the diaper package specifically says it's good for up to 10 pounds!"
