Driving Through Texas

Two men are driving through Texas when they get pulled over by a state trooper.  The trooper walks up and taps on the window with his nightstick, the driver rolls down the window and "WHACK," the trooper smacks him in the head with the stick.

The driver says, "What the heck was that for?"

The trooper says, "You're in Texas, son.  When we pull you over, you better have your license ready when we get to your car."

The driver says, "I'm sorry, officer, I'm not from around here."

The trooper runs a check on the guy's license, and he's clean. He gives the guy his license back and walks around to the passenger side and taps on the window.  The passenger rolls his window down, and "WHACK," the trooper smacks him with the nightstick, too.

The passenger says, "What did you do that for?"

The trooper says, "Just making your wish come true."

The passenger says, "Huh?"

The trooper says, "I know that two miles down the road you're gonna say, 'I wish that jerk would've tried that stuff with me.'"
