Remembered 1 more.
I had to get back at someone for playing a practical joke on me while I was asleep. I waited till he nodded off one warm and sunny afternoon following a barbeque and a fair amount of beer and then decorated his face with permanent marker. But not just any marker, oh no, it was a special pen that is used for marking steel girders with particularly indelible ink. The mess (which was photogrpahed and emailed to a fair few people) was there for at least 3 weeks.
