Cop pulls over a taxi.
Cop says: "Licence please."
Taxi driver says: "What for?"
Cop: "You didn't come to a complete stop at the stop sign."
Taxi driver: "I slowed down, and no one was coming."
Cop: "You still didn't come to a complete stop. Licence please."
Taxi driver: "What's the difference?"
Cop: "The difference is you have to come to a complete stop, that's the law. Licence please!"
Taxi driver: "Heish .... if you can show me the difference between slow down and stop, I'll give you my licence and you give me the ticket, if not, you let me go and no ticket."
Cop says: "Exit your vehicle, sir."
The taxi driver gets out of his taxi, whereupon the cop takes out his truncheon and starts beating the kak out of the taxi driver and says: "you want me to stop or just slow down?"
