Okay, I have one from my youth. I'm actually very upset that I can't think of anything more recent. I'm constantly doing silly stuff, and I pride myself on my willingness to offer myself up for the sake of a good laugh. I'll think of something, I'm sure.
Anyhow, as a child I had one big experience with vandalism. I was about 12 y/o and was staying the night at my friend's house for a slumber party. All the girls decide to go out "toilet papering" the neighborhood. Me, being the perpetual overachiever that I was, I set my sights on greater mayhem: glue. My friend had this super sized bottle of Elmers that fit the bill. We ran around the neighborhood. I came up with all kinds of creative uses for the glue. Then we all hit my friend's neighbor's yard. Yes, her neighbor. I decorated their vehicles with glue and toilet paper. What? It stays on better that way. Then I headed to the mailbox wondering if it would hold. As I was busying myself with glueing the gentleman's mailbox shut, I suddenly heard a scream, "Get the f*** away from my f***ing mailbox!" The whole party darts straight across the street and into our friend's house. Yes, we were accomplished criminals.

As I reached the front door, the police were pulling into her driveway.
We all rush into slumber party garb when the doorbell rings. The three policemen at the door explain the purpose of their visit. One of them holds up my super sized glue bottle and asks if it belongs to anyone. Oh yeah, I just threw it on the ground outside the door to my friend's house. The other policeman takes out his super flashlight and tells us to line up so he could check our hands. Needless to say, my hands were full of glue. I was the first person he checked because of my obviously guilty demeanor. I was cursed with a face that reveals my every thought. Anyhow, they tell me to step to the side because I was going with them.

One by one my friends were checked. One girl even managed to pass off the glue on her hands as dead skin. It turned out, I was the only one getting arrested that night. I was fortunate in that my friend's mother pretty much begged them not to take me. LOL Finally, they relented but not before they informed me that they would be taking fingerprints on the glue bottle. If it matched mine, they would be back to get me.
The following day, my mother came over to pick me up. As I get into the car, I see the neighbor standing across the street giving me the evil eye. As she's pulling away, she spots the neighbor and says, "Oh, look at who that is, it's so and so, I used to work with him at..." "He's such a nice gentleman. I really love that guy..." She was gushing for God's sakes.

I still can't understand how she missed the stare. I honestly don't believe he came over because of my mother.
I spent a month of sleepless nights waiting for the police to come and arrest me. I kept imagining this huge fingerprint database out there. Did they get mine? Was it a good set? When did they get it? At birth? And what about the glue bottle? Surely, there were some good prints there. How long did it take to run a fingerprint test? When would I know that I was in the clear? LOL It was at least a decade before I shared my story with my mother. Over ten years later, and she still became irate when I told her. Even today, I know she'd get extremely pissed if I were dumb enough to bring it up.
Anyhow, I think there is a myriad of stupid behavior in that experience. It did work out in my favor since I quickly learned that I'm not built for a life of crime. I tried a few more times, but I was never very successful.
