A HAIRY SITUATION Uncle Jack was going bald. One day, Mary, who was not known for her politeness, remarked to him, "I don't sup- pose that there is anyone in the world who has as few hairs as you do!" "Don't be silly!" said her brother, Gary. "The less hair you have, the more likely it is that someone has the same number. If you were completely bald, you would have the same number of hairs on your head as millions of other completely bald people. But I bet there isn't anyone with the same number of hairs on their head as I have," and he shook his thick hair from side to side. "On the contrary," said Uncle Jack. "It is quite certain that there are many people in the world with the same number of hairs on their heads as you have!" "You can't know that," said Gary, "because you haven't counted the enormous number of hairs on my head!" Uncle Jack just smiled.

Mary is a small girl going to school and back. When she enters the lift in the morning she can reach the bottom marked 'GROUND' but, on returning, she cannot reach any button higher than '5 th '. Only if an adult is getting into the lift at the same time can she ask them to press '16 th ' for her, and go all the way up.
