it doesnt fly
That's what I've heard, but don't listen to me I have no clue.
The person with the bigger bone gets to make the wish and their wish might come true.
Typically no. A broken jaw is when your mandible gets fractured (usually in two places). Your cheek is formed by the zygomatic bone, which is part of your fused skull. But the coronoid process of the mandible is right next to the zygomatic bone, so I guess it might be possible for both to get fractured in the same injury.
Then both wishes come true! YAY for everyone!
If the bone breaks into three pieces, such that neither person gets a piece of the junction, then neither person's wish will come true.

What happens when chicken bone gets stuck in gas tank
The person (or thing) most in need of help (or service) gets the help. Or... you fix the thing that's broken, by paying more attention to it than the things.
A promise is broken before it is held.
A wishbone is a bone that is found in a chicken and turkey. People use the bone to make a wish. Two people hold one side of the bone and whoever gets the smaller piece of bone is the winner and gets to make a wish.
