Skeleton Escaping Disease

Skeleton Escaping Disease is a rare condition where a human's skeleton regains its consciousness and tries to escape from the body while the person is still alive. The mortality rate is heavily debated. Some scientists say it's 100% while others argue it's 0% because one life has been replaced by another, balancing out the loss of a life, especially one more profoundly dumb than a skeleton (skeletons on average have higher IQ than their fleshy owners). One doctor, Boneless Tinslow, argues the mortality rate is 999999% because he hates skeletons.
