A giraffe walks into a bar and summons the bartender. "Hey you! Yeah, you! How come you stole my wallet?" demanded the giraffe. "Why I don't believe I did, Mr Giraffe" replied the bartender, taken aback. "Yes, you did sir. When the horse and the camel came in here several hours ago, they paid for their drinks with cash in a brown wallet that they eventually mislaid in this very bar. That wallet was originally stolen from my person. You, sir, found that wallet here and kept it for your own benefit" explained the giraffe. The bartender thinks a moment and says "The next animal that walks into this bar will get his head punched in."
