When someone at a funeral drops or knocks over the casket and the body of the deceased happens to come out. Although rare in it's nature, reports show that it can and has happened.
Jim: "How was the funeral dude, I am sorry for your loss"

Eric: "It would have been fine if my drunk uncle wouldn't have been a pallbearer. We had a Cadavalanche."
