Gammon v. Osteopathic Hospital of Maine, Inc:
The plaintiff's father, Linwood, died in the defendant's hospital. A funeral home was called in to "make the arrangements".
The plaintiff received a bag that was supposed to contain his father's personal effects. Instead it contained a Severed Human
Leg!
He yelled:"Oh my God, they have taken my father's leg off!" and ran into the kitchen where an aunt testified that he "was white as a ghost." It was later determined to be a pathology specimen which belonged to another person.
Thereafter plaintiff "began having nightmares for the first time in his life, his personality was affected and his relationship with his wife and children deteriorated."
He sued and won.

Wallace v. Coca-Cola Bottling Plants, Inc.:
A man purchased a bottle of Coke, opened it normally and heard a fizz. He put it to his mouth and felt something in it. He poured it out and found an "unpackaged prophylactic".
He also won.

Not from a case, but an actual occurrence reported in the San Francisco Examiner Jan. 7, 1995

In 1995, in New York City, as a man held the door of an elevator for an exiting woman on the second floor, a second woman caught her foot. As the man moved to free her, the elevator suddenly lurched upward with its doors still open. The movement decapitated the man sending his body to the hallway floor while the elevator continued up to the ninth floor with other passengers and the decapitated man's head--with Walkman earphones still attached!
