Arthur Kennicut and Lt. Columbo in “Unfinished Business”

What would you have done if the car hadn't broken down? You couldn't set up this trap.

Lt. Columbo

Well, I guess we would have found some other way. You know what this place reminds me of, just seeing all these cars? You know, in our neighborhood we had a bunch of jokers. I mean we were a real loud bunch of guys and we figured out a perfect way to put a car out of commission. You take a potato, you stick it in the exhaust pipe. Doesn't cause any damage but the car won't start. It was a terrible thing to do. And I got a feeling that the reason I became a cop was to make up for all those jokes I played when I was a kid.
