Sherlock Holmes and Dr. Watson went camping. They pitched their tent under the stars. During the night Holmes wakes Watson and says. “Watson, look up at the stars and tell me what you deduce.”
Watson answers, “I see millions of stars. It’s quite likely some have planets similar to Earth. And if there are planets like Earth there might also be life on some of them.”
Holmes replies, “Watson, you idiot. Someone stole our tent.”
