Famed fictional detective Sherlock Holmes and his gruff assistant Doctor Watson pitch their tent while on a camping expedition, but in the middle of the night Holmes nudges Watson awake and questions him.
HOLMES: Watson, look up at the stars and tell me what you deduce.
WATSON: I see millions of stars, and if there are millions of stars, and if even a few of those have planets, it is quite likely there are some planets like earth, and if there are a few planets like earth out there there might also be life.
HOLMES: Watson, you idiot! Somebody stole our tent.
