Some of these responses are hoots! IIRC the OP was looking for bad things to say, so I’ll contibute this thought: “Are you Barney or Andy?”
[slight hijack] While driving through bohunk Kansas several years ago, I was attempting to escape a snowstorm coming out of Colorado by diverting south to I-40 instead of I-70 which I’d been following.
Following locals for miles and tasting the edge of town, I see a break and kick it up a notch, pass 3 cars and rip out of town. Blinkies appear in my mirror from the distant past, as I’m now travelling at 85, passing an occasional vehicle, several miles from bohunk.
Once the blinkies close to within a half mile, I drop speed to 70 (the posted limit) and hope to be passed. Not so. Window down, radio off, and thumbs hooked under the wheel, all digits up, I watch in left mirror as the officer approaches with hand on service pistol.
He asks if I know why he’s stopped me.
“Sure, I was speeding.”
“No.”
“Sorry, Sir, then I’m stumped.”
“I’ve stopped you for passing those three cars back in Pewee Flats. You hadn’t completed your pass safely before the passing zone ended.”
“PeWee Flats? That was 10 miles back up the road!”
“I’ve been doing 100 MPH trying to catch you!”
“Well, Sir, didn’t I start this conversation out by telling you I was speeding?”
The Officer started laughing, ran my cards, and gave me a warning, with a smile.
