I too am extremely sensitive and do not like pranks. I am easily embarrassed, and don't like to see others made the brunt of a joke either. Some people take it well though, and that's great. Many pranks often go wrong.
The best prank I ever pulled was on a student. This particular young man -I'll call him "Mike" - was always a pain in the neck in class, forever coming up with little ways to annoy everyone. He would hide things, rearrange stuff on my desk, make obnoxious noises, question every little thing just to waste time, and so on. Finally I told him that I had thought of a way to get even with him, and that I was going to do it on April Fool's day. For weeks I gave him the countdown; every time I saw him, it would be "Hey, Mike, only x days left until April Fool's day!"
The joke was that I didn't have anything planned for April Fool's day. It was all about the suspense. And it worked, too...Mike cut school on April Fool's day, telling his friends he was so afraid of what I had planned for revenge that he didn't dare show up.
In college my friends and I stole the underwear out of the dryer in the common laundry room. We knew who the underwear belonged to, so we sent him one pair a day through campus mail. I don't think he ever learned who did it, but we laughed when we heard through the grapevine that he wished that "whoever is sending my underwear back to me would send two pair per day -- I like to shower after I work out."
Remember, funny pranks can have terrible results. When I was in college, I had a friend who worked in a funeral home. We thought it would be funny to create a fake obituary announcement for me. We had it printed up--a small, folding card--and I posted it on my apartment building bulletin board. The next thing I know, my father is calling me, hysterical that I had died without him knowing (we hadn't spoken for a week or so). The apartment manager had seen the announcement, called my parents, and nearly given them heart attacks. My friend at the funeral home was persona non grata with my parents for many years. I still have a copy of the announcement to remind me of this joke gone awry.
We played one in fifteh grade. Me and my science teacher were close back then and the entire class had gone on a trip to the woods for a week and we were all heading on our way to the sampfire because that was next on our schedule. We had been warned not to bring food j to cabins because there were bears and deer and stuff roaming freely and some of the girls were terrified so anyway we geabbed tree branches and posed people in the legs while they were on their way to the campfire. No harm was done but it was a bit funny.
One of my cabin mates also pranked me. So there were 2 rooms with beds and a very small middle hall that was attached to both rooms and the monitors room and in the hall we had a mirror that was positioned so that you could see the second room in the reflection. These cabins were very old as well so all the girls decided not to sleep in the 2nd room since every time someone stepped in there the one pair of bunkbeds would start creaking so we called it the haunted room and it was assumed nobody went in there. I walked in the cabin to fix my hair I was looking in the mirror combing it when my friend who is deathly pale slowly slid out from the 2nd room and I screamed and nearly got a heartattack. We laugh about it now.
