A hairy situation
The two desperadoes
Uncle Jack was going bald. One day, Mary, who was
not known for her politeness, remarked to him, "I
don't suppose 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
else has the same number.
If you were completely bald, you would have
the same number of hairs on you head as millions
of other completely bald people. But I bet there
isn't anyone with the same number of hair 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 enomous number on my
head!"
Unce Jack smiled
Why was uncle Jack so confident?
Jake was grinning because he had switched the
white ball for another black one, so Guts was bound
to draw a black ball and die. But if the boss agreed
to Jake showing the second ball – which was
bound to be black - Jake would be in trouble as his
trick was discovered!
