This is a great thread! What a good idea!
My Grandma Mamie told me the one about 'A whistling girl and a crowing hen - both will come to some bad end.'
And in Tennessee it's black-eyed peas, turnip greens, and cornbread on New Year's Day for good luck and prosperity - never had the pork or hog jowls, tho - maybe some corned beef? which I don't care for either.
What else? If your ears are burning, someone is talking about you.
If you raise your feet for someone to sweep under them, you'll never get married.
