"Was I speeding, officer?", asks the driver.
The cop whacks the driver on the head with the nightstick.
"Ow!", exclaims the boy, "What was that for?"
"Son, people in this state respect the Law. When an officer of the Law pulls them over, they have their driver's license, registration and insurance ready and the window down!"
So the driver hurriedly pulls out the required documents and hands them to the cop.
"You were doing 5 miles above the speed limit and I would normally drag your asses down to the station, but seeing that you're from out of state, I'm gonna let you go with a warning this time.", the cop says, and hands back the documents.
Then he walks around the car to the passenger side, and taps on the window with the nightstick. The passenger rolls down his window.
The cop whacks him on the head with his nightstick.
"Ow!", exclaims the boy, "What was that for?"
"I was making your wish come true!"
"What wish?"
"Oh, about a mile down the road, you were gonna say "I wish that f***** cop would've tried that bullshit on me!"
