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

The driver says, "Why'd you do that?

The trooper says, "You're in Texas, son. When I pull you over, 
you'll have your license ready."

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 the trooper smacks him with the 
nightstick.

The passenger says, "What'd you do that for?"

The cop says,"Just making your wishes come true."

The passenger says, "Huh?"

The cop says, "I know that two miles down the road you're 
gonna say, 'I wish that sucker would've tried that shit with me!'"
