Don't you hate it when this happens?

At the UPMC Presbyterian hospital in Oakland, Pa., a 35-year-old man having a kidney transplanted from his mother awoke prematurely from his anesthesia and bolted upright, which caused the just-sewn-in kidney to thrust up with such force that it ripped an artery and protruded from his abdomen. The kidney could no longer be used and was removed the next day. Source.
