A Philadelphia police officer pulls over two young men on Broad Street. The officer walks up to the driver's window and taps on the glass with his billy club. As soon as the driver rolls down the window, the officer smacks him in the head with the billy club. "What was that for?" asked the driver. "Son, when I pull you over you have your driver's license and registration ready when I come up to the window," replied the officer. The driver, rubbing his head, gives the officer the necessary paperwork.
The officer returns a minute later with a written warning. As the officer hands the paperwork back to the driver, the officer again smacks the driver in the head with the billy club. "What was that for?" asked the driver. "Son, when you drive in my city, you had better be following all of the laws. This time I'm just writing you a warning."
The officer then walks around to the passenger's window and taps on the glass. The passenger rolls down the window, and before he can say anything, the officer smacks him in the head with the billy club. "What was that for?" asks the passenger. "Son, I just made your wish come true," replied the officer. "See, a mile down the road after you drive off, you're going to say, 'I wish that pig had tried that **** with me.'"
