My neighbor used to leave a silver dollar (a REAL silver dollar) on the back porch overnight on New Year's Eve. If it was still there in the morning, you were supposed to have a good year.
NOT A HOLIDAY STORY:
A regional prosperity preacher used to have you give him a five dollar bill (or a ten, or twenty if you didn't have a five). He would "bless it" and give you back a one dollar bill. He said as long as you kept that dollar in your billfold, you'd never be broke.
When I pointed out to a friend that it was a scam, she said, "What should I do with the dollar?" I said, "Spend it or give it away as fast as you can."
We now return you to a more edifying discussion.
