A bystander on a street corner pulls out his cell phone and excitedly reports a major robbery of the Jewelry store right next to him and he's a witness. In a few moments the police arrive to find the front window of the store totally smashed in and most of the jewelry on the display shelves gone.
They take pictures and pull out their notebooks to interview the witness who called in the robbery. "Exactly what happened sir?"
The man answers, "Well I was standing here waiting for the bus when this big truck pulls up, the back doors open up, a ramp swings down to the street and an elephant walks out.
"Then the elephant bashes his head through the store window and sucks up most of the jewelry in his trunk. Then he gets back in the truck, the ramp goes up, the doors close and the truck drives away".
The stunned police officer says, "Wow! That is certainly amazing and very unusual. This is going to take a lot of detail questioning. Before we get to the truck description, was the elephant an African elephant or an Asian elephant?"
The witness stammers, "Uh, I don't know. What's the difference?"
The officer says, "Well an African elephant has very large ears like big butterfly wings and the Asian elephant has much smaller ears."
The witness shrugs his shoulders and says, "How would I know THAT? He wore a stocking over his head."
