A police officer pulls over a driver.
"Sir, you were speeding. May I see your license and registration, please?"
The driver responds, "I'm sorry, but I lost my license for drunk driving, and I don't have the registration papers because I stole this car."
"Stole it?" the officer asks.
"Yes, and I killed the owner. In fact, she's in the trunk if you'd like to see."
At this point, the officer backs slowly away and radioes for backup.
In minutes, five police cars are circling the car, and a senior officer slowly approaches the driver.
"Sir, could you step out of your vehicle, please!"
The driver does so. "Is there a problem, officer?"
"One of my officers told me that you have stolen this car and murdered the owner."
"Yes. Could you open the trunk, please?"
The man opens the trunk, which is empty.
The officer says, "Is this your car, sir?"
"Of course," the man says, handing over the registration papers and his license.
"Sir, my officer said you did not have your license or registration."
The man replies, "I'll bet you the liar told you I was speeding, too!"
