Slow Down Or Stop :

A guy runs a stop sign and gets caught by a policeman.

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, "Exit your vehicle, sir." At this point, the cop takes
Out his nightstick and starts beating the shit out of the guy and
Says,

"Do you want me to slow down or stop?
