I got to school one day and noticed 6 trees all indoors and lined up neatly in a row. The first thing I thought was about how the pollen from those trees really irritates my allergies. Then I remembered that modern day Christians kill trees to bring them inside as a Christmas decoration. This seemed odd to see in a school cafeteria because public schools really aren't to favor one religion over another. Thinking on this for some time I suddenly had an overwhelming desire to write "nondenominational tree" on a piece of notebook paper and place it upon one of the trees. This desire was more from my twisted sense of humor than from any sort of political statement.
My prank completed I then went about my classes and checked back on my piece of paper in a few hours. I had simply placed the paper on a branch as it was some sort of ornament. When I returned I discovered that someone had torn a whole in the paper to spear through with a branch to better hold the paper in place. Now I thought this was rather funny and told my friends. Since this was Friday and the building wouldn't be open again till Monday I was rather curious what happened to my sign and checked back early. To my surprise not only was the sign gone but so were the trees.
A friend of mine who worked at the campus started complaining about how he spent most of the weekend in a meeting about this sign someone wrote and left on a tree. He was rather upset about the whole thing and how so many people wasted their weekend debating a piece of paper. Boy was he upset when he found out that I had wrote the sign. He did agree that it was funny at first but about hour 6 of the meeting he was really getting upset about it. Many of the people didn't think they could remove the sign while others just thought that it was a piece of paper and this whole thing was a gigantic waste of time. So due to a small prank that was designed to only make people think and not cause any damage to the university. I still managed to cost the university a lot of money.
All in all it was still a good joke.
