The FBI, DEA and CIA all argue that they are the best law enforcement agency in the world, so to find out once and for all which of them really is they devise a competition.

 

They release a rabbit into a forest, and whichever agency finds it first will be declared the best.

 

The FBI goes first. After two weeks of interviewing plants and animals, the FBI concludes that no rabbit has ever existed.

 

The DEA goes next. After burning down half the forest and defoliating the rest, they also find no rabbit.

 

The CIA goes last, and after a few moments, agents drag out a badly beaten bear, screaming "Ok, Ok! Yes, I'm a rabbit!"
