Where do you crazy kids get these pigs? Seriously.
One class's senior year coincided with a majestic time in mid-Maryland which is the fourteen-year cicada swarm. I can't explain it to its proper justice but imagine cicadas, EVERYWHERE. I shit you not, for about a week or two there are just tons and tons of the things all over. Some of the students collected a bunch and just let em fly around in the school it was pretty anticlimactic.
Heard stories of years past people moving the portable classrooms onto the football field etc.
Thinking of lots of little stupid things, but whether or not they're more funny or cruel is certainly up for debate. Personally, I'm more fond of customized pranks that take advantage of a particular staff member and one of their quirks. We had a social studies teacher who, every day, we would try to find a new place to hide his coffee mug. Probably the longest it took him to find it was when we hung it out the window, which was on the third floor.
More juvenile things would be like seran wrap on toilets. Could also do something like get a bunch of seniors during lunch period to pop an alka seltzer in their mouth at the same time and pretend to spazz out. Everyone could just try randomly sitting in on the wrong classes to see how long it takes a teacher to notice.
Couple that were done throughout the years when I was in high school were reversing the handles on a bunch of the doors in the school, filling up an entire bathroom waist high with paintballs, filling the main office with hundreds of empty pizza boxes. Someone had somehow got a hold of a list of all the locker combination's in the school, and they changed everyone's locker combination. Few other minor ones, but those were the ones that stuck out.
I had a really small highschool(one "big" room and then 13 small classrooms branching off it), but I'm sure you could adapt these somehow. Basically my Junior year, the entire big room was filled with balloons with the hallways blocked off with plastic sheets. This one took forever though because we had to start at like 6pm afterschool to start filling balloons into an RV, which we drove over and unloaded to save time, and finished at like 6am. For my senior year, we basically got a disassembled car in enough pieces until we could fit it through the front door, then reassembled it in the middle of the school with streamers and shit all around.
Both of these were pretty well received by the classes, but mostly because the school let us have a balloon popping fight to get rid of the balloons then left the car there for like a week, where people found all sorts of ways to do shit with it like eat lunches off/in it.
Kind of late for you to do it exactly how we did it.. one of the girls in my class her mom was a biology teacher at our school as well with access to the principals office. Everyday from the day we started to the day we did our senior prank she went into his office and grabbed all the papers he was throwing out that day and shredded them..
by the time we did the senior prank we had accumulated 100+ 50Gal trash bags full of shredded paper, all from his room. We took all of the shredded paper and filled his office full of it, leaving just enough room for us to get out of the top. Was great seeing how there was a little window facing towards the courtyard so everybody walking by could see the paper filling the windows. I'll post pictures later!
My school had one of those water fountains in the main dinning area. We dumped 25 of these

in there.
people actually do senior pranks?
All the destruction shit and pranks that involve shit and piss is not funny at all. We had 173 in our senior class. We had everyone get an old alarm clock and set them a minute apart and then put them in our locker. It may not sound like much but a 100+ alarm clocks going off in one minute intervals is pretty fucking loud.
If you really want to surprise the shit out of them, use the prank below at your own risk:
Spoiler: show
Thousands of cups, cardboard. Fill Cups with water or whatever, place cardboard on top, flip them over, pull cardboard out. Place cups everywhere.
These pranks all suck.
EDIT Beaten.
Beaten to what? Saying all the pranks sucked? Because I know mine sucked it would be the internal satisfaction the most. "What is this cup.. *pick up* oh dammit"
We fiddled around with the sink in the cafeteria so that it would keep running and would not turn off. We then dumped in about 20 Gallons of bubble mix into said sink and let the water run. Most of the main floor was covered by bubbles for the rest of the day, and they had to close off the caf because the wall of bubbles was 6 feet high and you could not see anything.
Vandalism pranks are retarded. Filling like 10 random lockers with styrofoam peanuts would be entertaining. After the first 2 or 3 times someone opened their lockers and that shit poured out, no one would want to open theirs for the rest of the day.
Have the entire male section of your senior class all take Viagra at the same time and then wear very loose fitting shorts so its obvious you all have massive hard-ons.
