The other day at school a girl was cracking her neck during class, she turned her head one way with her hands *crick!* then the other way *crick!*; except on the second crack she let out a cry, she had literally broken her own neck. Ambulance, stretcher, whole deal. I don't know if she's okay or what, she probaly is, but it's a good story to hear in case you are the kind of person who likes to crack their necks, now you'll think twice.
