About 3 years ago I was out doing my routine run/walk during one afternoon. I got a stitch in my side and stopped to catch my breath. The neighborhood I was in was familiar to me but about 3 miles away from my house. Apparently I "ducked" out of sight behind a car (I hunched over at the waist trying to stretch out my cramps and stitch) just as a pair of cops came around a corner. They immediately chirped their siren as they pulled up to me and it honest to go startled me. I "reacted in a suspicious manner" and questioned me for a few minutes before they put me in handcuffs and roughly into the backseat of their patrol car.
As I had nothing to hide, I answered all their strange questions as to why I was in this neighborhood, in the middle of the afternoon, out of breath and attempting to hide from the police. "I was running for exercise, I work '2nd shift' so I don't work 8-5, again... running... see my running app history for proof, and I wasn't hiding, I was taking care of a stitch in my side."

They kept me handcuffed in that patrol car for nearly 30 minutes until they finally had to left me go. "Don't let us catch you in this neighborhood again" was how they tried to power trip me. I was 100% respectful and courteous towards them the entire time until that point. I casually told them "No, I don't think so.. I run this routine 3 times a week. It's a public street. Thanks for your suggestion but No.".

In the fourth grade, on a military base in Texas, I used to ride my mothers bicycle off the base to the local comic book store, and spend my entire allowance on comics. I would then spend the rest of the week selling these comics to the rest of my fourth grade class, for double the cover price... I got to read all the comics, and made a healthy profit on them as well.
One day my teacher Mr Smith found out about my scheme, and confiscated my entire collection of comics. They weren't disrupting class, as I sold them before and after school, and I had them in a paper sack in my desk, like I did every week. I was as angry as a ten year old could get.

So I gathered all the money I had (ten bucks!) and went to the local commissary. I bought all the bulk penny candy I could. It ended up filling a grocery sack about half full. That's a LOT of candy. Then the next day, I smuggled it into the school.
I showed it to all the kids before the day started, and announced anyone who got yelled at, got a handful, and anybody who got sent to the principles office got FOUR handfuls.
Chaos ensued, as I sat back and watched, angelically glaring at Mr. Smith. On the second kid sent to the principles office, I got ratted out.

The principle sent for me and Mr Smith together, and someone else took over the class. Once in the office, the Principle asked me what was going on... I explained in detail, still angry, speaking in clipped terms what Mr Smith had done, and how I would keep making his life miserable till I got my comics book back, and I glared at both of them with little hands folded in defiance.
When they sent me out of the room, I could hear both of them break out in uncontrollable laughter.
I got my comics back.
