When I was a kid and my mother made chicken or turkey, my sister and I got to break the breastbone. Or wishbone as we liked to call it. Whomever scored the keel bone got their wish.
It's weird, but I can't make myself throw these things away. So if you ever come to my house and are in need of some luck, some mojo, or just want a bit of friendly competition, Just ask. Seriously. These things are starting to pile up.
