Probably not a good idea. I've also determined that avoiding a speeding ticket by asking the cop: "What's the matter, is Dunkin Donuts closed?" is not a good idea, either.
When we were kids (ca late 40s), when we saw a cop, we’d yell, from a distance, “What’s the color of a penny?” and the other kid would yell “Dirty Copper!” and then we’d run like Hell.
That worked until one neighborhood cop (we had them in those days) recognized us and told our parents. When I got home the Old Man spanked the crap out of me (CHILD ABUSE! :-) )
