The LAPD, 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 FBI goes in. They place animal informants throughout the forest. They question all plant and mineral witnesses. After 3 months of investigations they conclude that rabbits don't exist.
The CIA goes in. After 2 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 two hours later with a badly beaten bear. The bear is yelling: "Okay! Okay! I'm a rabbit!"
