In an effort to determine the top crime fighting agency in the country, the president narrowed the field to three finalist, the CIA, the FBI, and the Chicago Police.
The three remaining contenders were given the task of catching a rabbit which was released into the forest.
The CIA went into the forest. They placed animal informants throughout. They questioned all plant and mineral witnesses. After three months of extensive investigation they concluded that rabbits do not exist.
The FBI went into the forest. After two weeks without a capture, they burned the forest killing everything in it, including the rabbit. They made no apologies. The rabbit deserved it.
The CPD went into the forest. They came out two hours later with a badly beaten bear. The bear was yelling "Okay, Okay, I'm a rabbit, I'm a rabbit".
