WHACK!

Two men were driving through New Jersey when they got pulled over by a State Trooper. The cop walked up and tapped on the window with his nightstick.
The driver rolled down the window and WHACK," the cop smacked him in the head with his nightstick.
"What the hell was that for?" the driver asked.
"You're in New Jersey, son," the trooper answered. "When we pull you over in New Jersey, you better have your license ready by the time we get to your car."
"I'm sorry, officer, " the driver said, "I'm from New York and didn't know your laws here."
The trooper runs a check on the guy's license -- he's clean and gives the guy his license back.
The trooper then walks around to the passenger side and taps on the window. The passenger rolls down the window and "WHACK," the trooper smacks him on the head with the nightstick.
"What'd you do that for?" the passenger demands.
"Just making your wish come true," replied the trooper.
"Making WHAT wish come true?" the passenger asked.
"Because I know you New Yorkers," the trooper says, "two miles down the road; you're gonna turn to your buddy and say..... 'I wish that jerk would've tried that crap with me!'"
