A jeweler called 911 and said that his store had been robbed.
“Did you get a good look at the thief?” asked the dispatcher.
“Yes,” said the jeweler. “It was an elephant.”
“I see,” said the dispatcher. “Was it an African elephant or an Asian elephant?”
“What’s the difference?” asked the jeweler.
“The African elephant has much larger ears than the Asian elephant,” said the dispatcher. “So was it an African elephant or an Asian elephant?”
“How the heck should I know?” said the jeweler. “He had a stocking over his head!”
