The KGB, The FBI, and the CIA are all trying to prove that they are the best at apprehending criminals. The President decides to give them a test. He releases a rabbit into a forest and each of them has to catch it.
The CIA goes in. They place animal informants throughout the forest. They question all plant and mineral witnesses. After 24 hours of extensive investigations they conclude that rabbits do not exist.
The FBI goes in. After two hours with no leads they burn the forest, killing everything in it, including the rabbit, and they make no apologies. The rabbit had it coming.
