A young man asked an old rich man how he made his money.

The
old guy fingered his worsted wool vest and said,
"Well, son, it was 1932. The depth of the Great Depression.
I was down to my last nickel. I invested that nickel in an
apple. I spent the entire day polishing the apple and, at the
end of the day, I sold the apple for ten cents. The next morning, I invested those ten cents in two apples.
I spent the entire day polishing them and sold them at 5:00
pm for 20 cents. I continued this system for a month, by the
end of which I'd accumulated a fortune of $1.37. Then my wife's father died and left us two million dollars."
