Brutus asked his grandfather, "Grandpa, how you become so rich?"
Grandpa: "Well, son, it was 1928 - time of the Great Depression. I was lost in financial crisis. I invested $10 in buying some chocolates. I sold them for $50. Again, next day I bought apples pricing $40. I again sold them at a profit. I had made up roughly $40 in one week. In the meanwhile, my wife's father died and left us 100 million dollars."
