I had a boss when I was a kid that was crushed in a loader... you know... where it articulates. I guess he went up to talk to the operator, but the operator didn't notice. When he got to the hospital he told the Dr; "See this bone here? (pointing to his pelvis) It's broken twice." When the Dr came back from looking over the x rays he said; "how did you know that!?" "I heard it break twice" He said he was in so much pain that if he could have made it out of bed to the window he would have jumped out.
Not quite related, but reminded me.
