All of these examples are shown for comedic effect.
Shorts:
A woman is shown on fire (in a REALLY cheesy special effect), and is shown in a full-body cast. She is later said to have been disfigured as a result.
Animated blood in one short.
A cartoon depicts an young animal passing out in the cold and his father putting down a grave. The same animal is later mauled by a polar bear off-screen. The father puts down another grave. The father is then attacked by a polar bear. This is all done in a goofy fashion.
Reefer Madness:
A man is hit by a car.
