The CIA, the FBI and the KGB argue about who’s the best at catching criminals.
The Secretary General of the UN decides to test them. He releases a rabbit into the woods and each of the divisions has to catch it.
The CIA goes in. They place animal informants throughout the forest. They question all plant and mineral witnesses. After three months of extensive investigations they conclude that rabbits don’t exist.
The FBI goes in next. After two weeks with no leads they burn the forest to the ground, killing everything in it, including the rabbit, and they make no apologies. That rabbit had it coming.
The KGB goes in last. They come out a few hours later with a badly beaten bear. The bear is screaming: “Okay! Okay! I’m a rabbit! I’m a rabbit!”
