A man reading a magazine in his sitting room sat opposite his son, who was having dinner. He, the son had two cakes in his plate. After watching his plate for a while, he said to his dad,
"Daddy, I can prove that there are three cakes in ma plate,"
"Go ahead," his dad urged him. So the son pointed at the first cake and said,
"This is one," Then, pointing to the third, he said,
"This is two. One and two make three."
"Genius," his father praised. "Now let me have the first cake, your mother the second and you the third."
