Sherlock and Watson are out camping. In the middle of the night, Sherlock wakes Watson up.
"Watson, please look up and tell me what you deduce."
"Well, my dear Holmes, I observe the awesome size of the universe, and the vast multitude of stars shining down on us. If we assume that even a small percentage have planets capable of supporting life, I deduce that somewhere out there, life must indeed exist."
"Watson you idiot, someone's stolen our tent!"
