The bread and the cat

Old grandma stories never seem to lose their value. One of those is the story of a piece of bread and the shrewed cat. One day two monkeys stole a piece of bread from a shop and were fiercely fighting over it. A shrewed cat kept watching at first then went to help them out. She took the bread, cut it in two pieces - one bigger than the other. One monkey objected to see the other getting the bigger piece. Cat ate the smaller one and did the same for the bigger piece again. She kept doing it till she ate it all. Whatever the era is it seems some monkeys never understand this story.
