squirrel elbow 

Originally from the inner cities of New York this disease is passed on from squirrels to humans when sleeping. The human elbow emits an odor that confuses these inner city squirrels in to thinking the elbow is in fact another squirrel. In turn the squirrel tries to hit it, but first nibbles on the elbow as foreplay. The elbow then becomes pregnant or infected. If you have ever seen someone with an abnormally large elbow, theres a 90% chance are they are a victim of this disease. If the elbow is not treated soon enough, it will never stop growing.
