Mission: go to the forest, find and catch a rabbit.
CIA 4 hours later: "We interrogated every our source, every bush and stone. After careful investigation we draw a conclusion that rabbit doesn’t exist at all."
FBI 24 hours later: "Rabbit has escaped. But it couldn’t make off too far."
KGB 20 minutes later: Got a bear, beat him within an inch of his life and the bear says: "I am a rabbit. My mother and father were rabbits."
