Imagine the following scenario:
Bob the construction worker and Lloyd the banker are neighbors. Bob's savings consist of 2 gold coins. Lloyd's savings consist of 10 gold coins.
One day, the god of thought experiments (GOTE)shows up with 100 coins. He takes Lloyd's coins and Bob's and puts them in a bag with his 100. He then tells Lloyd that he can divide the 112 coins between himself and Bob any way he wants. Bob can then either accept the distribution of coins or GOTE will take all 112 coins and leave Bob and Lloyd with nothing.
