I got a cop to laugh once.
I was pulled over early morning, just topped off fuel tank and picked up some coffee. I was taking my first sip of coffee while cresting a hill at a high rate of speed. (wasn't thinking just got on road and was thinking about my coffee and the long trip ahead)
Cop was on other side of hill. I passed him and he got in behind me quickly. We pulled over, he reached my window and I said "I was hoping there was a wreck up the road".
He stopped looked confused and said What? I said it again, then explained when I saw him come up fast behind me it was either a wreck up ahead or he was chasing me.
He actually laughed and put away his ticket book. He said he though he had heard them all, commented on I just came up with a new one. I explained I was preoccupied by my coffee and apologized for speeding.
He said slow it down, then walked away.
Nice encounter, glad cops are still human out there.......... We all make mistakes no harm no foul. A warning is enough sometimes.
