dunno if its been posted before, but i dont care much either.

A guy blows a stop sign in Philly and gets caught by a policeman. The cop says, "License and registration please."
Guy says, "What for?"

Cop says, "You didn't come to a complete stop at the stop sign."

Guy says, "I slowed down, and no one was coming."

Cop says, "You still didn't come to a complete stop, license and registration, please."

Guy says, "What's the difference?"

Cop says, "The difference is, you have to come to a complete stop. License and registration, please!"

Guy says, "If you can show me the difference between 'slow down' and 'stop', I'll give you my license and registration."

Cop says, "Okay, exit your vehicle, sir." At this point, the cop takes out his night stick, starts beating up the guy and asks, "Now, do you want me to slow down or stop?"
