What have you done just to fuck with someone?

In my early 20s I had a friend (believe it or not) that was a security guard at a hotel. He was the lone security officer at night.

He took his job a little too seriously.

One night my other friend ( I did have two friends) and I took his car apart while it was parked in the parking lot of the hotel. My security guard friend was working.

The poor bastard left his car unlocked. We took everything we could and unhooked / removed it placing the item in the empty space next to the car. The dumbass security officer friend left tools in the trunk so we used those, too.

We didn't fuck with anything that had to do with safety but we wanted to make a point.

The battery? Removed. The radio. Removed. Car seats? Removed. Every piece of change? Removed. I can't remember what else but it took dude a few hours to put everything back together. Yes, we stayed just to watch and make sure no one stole anything.

He still had balled up free press papers we used a few nights before to fill his unlocked car up making it impossible for him to get in. He was home and in his apartment but left his car unlocked.
