I have two:
One, when I was going to get engaged, I carried the ring around with me for about a month. I got pulled over twice to which I explained that I had just gotten an engagement ring for my girlfriend and I was sooo excited to get home and give it to her. They both let me off. I have thought about buying another cubic just to carry around for that
The second is that I have gotten assertive with officers. Not when I have been drinking, you can't win that one. but when they pull me over, they had better know what for and have evidence. I have been pulled over 5 times, some for clear violations like the inspection sticker, other less clear like speeding and they have let me go...every time.
