Would A Policeman Arrest You For This?:

Ok, on a night there is a roadblock in a good spot in town...drive through it.

Then, go to a friends house and get in another vehicle. Then, either drive a back road or get in the back seat so you can get turned around to go through the roadblock THE SAME WAY YOU JUST CAME in order to get the same cop. Let him check your liscense (again) and drive to someone else's house and repeat.

See how long it takes before the cop says anything about you coming again....but in a different vehicle.

I think it's funny.
