I have one that wasn't intended to be a prank, it was to be a revenge kinda thing.
No video.
But, this is what happened.
This guy at a place I worked at, and who also make alot more money than I did was constantly stealing my "smart food" popcorn and drinking off my open cokes.
This went on for some time, and I was pretty sure I knew who the culprit was, but not sure enough to make any accusations.
Sooooo, I took some styrofoam packing peanuts and mixed them in with some "smart food" popcorn that I had left out.
Sure enough, not 20 minutes later I hear the culprit spitting and swearing from out back.
It was him, and he couldn't deny it, as I had also taken a nail and put a couple holes under the opening of the coke can I had strategically left nearby for him to wash down the "smart food".
I had effectively marked him as the culprit with my dribble can of coke.
Now as I pointed and laughed, you can imagine my shock when he asked, "hey man, ya got a smoke?
