[edit] People

Faking or exaggerating an injury is a form of malingering and may allow a person to receive compensation, injury cover, or may result in a team being awarded a penalty in a game of football.

[edit] Animals

An opossum will feign injury or death to escape predators

The phrase "playing possum" is derived from the behaviour of the opossum, a mammal which will mimic the appearance and smell of a sick or dead animal when threatened. Birds such as the killdeer are known to feign injury to lead a predator away from their nest. The predator gives chase, believing them to be easy prey, but the bird then flies away, hopefully having distracted the predator sufficiently to prevent it from finding its nest.
