Old joke. New setting. A backpacker is walking through a town when all of a sudden he is hit from behind by a man who then proceeds to grab his backpack and yell, ""Thief! Thief!"" Police soon arrive and detain both of the men. Both of whom claim that the backpack is theirs. The sheriff of the town, clever as he is, lays the backpack before the men and asks them to describe the contents. The man who gets it right is clearly the backpack's owner. The backpacker begins to speak, but the thief loudly yells over him, ""THAT BACKPACK IS MINE!"" ""So what is in it?"" asks the Sheriff. ""In my pack, you will find four thousand, three hundred dollars. Three large bricks of marijuana. A water bottle containing my own urine, which you can test to prove it is mine. A deck of cards. Three McDonald's collector's edition plates. The ear of a man that I killed yesterday. And four venomous scorpions, which I use to guard my property."" The Sheriff's jaw hangs open... and he turns to the backpacker. ""Wha... What did ... Did you have in the pack?"" The backpacker looks at the thief and exclaims, ""This man is insane. That backpack is mine. And it holds nothing more than my property: A stack of forged passports, two submachine guns, 20000 dollars in gold, a Rolex watch, which can shoot a laser from the crown, my pet ferret Rocky, and an explosive device, which is currently not armed."" The Sheriff gulps. And then asks his deputy to open the backpack... which he does very gently with a stick. Out of the pack falls a sandwich. The backpacker says ""Huh... I guess it was his after all."" And walks off.
