The CIA, The FBI and the NYPD are on a training exercise together.
They are told to go in to the woods and bring back a squirrel.
The FBI goes first.
They come back empty handed.
“There were no roads or streetlights, our shoes got dirty and our suits got torn so we gave up”
Then the CIA go in.
They come back empty handed.
“We found a squirrel, but it was a low grade one so we turned it in to an asset and are waiting for it to lead us to the top squirrel in the organisation”
Then the NYPD go in.
Ten minutes later they come out with a rabbit with two black eyes.
“I confess, I’m a squirrel!”
