The LAPD, the FBI and the CIA were all trying to prove that they were 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 into the forest. They place animal informants throughout the forest. They question all plant and mineral witnesses. After three months of extensive investigations, they conclude that rabbits do not exist.
The FBI goes in. After two weeks with no leads they burn the forest, killing everything in it, including the rabbit and they make no apologies. The rabbit had it coming.
The LAPD goes in. They come out just two hours later with a badly beaten bear. The bear is yelling: "Okay, okay, I'm a rabbit!"
