I LOVE SENIOR PRANKS
My sister's senior prank (probably the best one I've ever seen, I was a sophomore at the time)- about 50 kids, the fastest ones in the grade that were all varsity athletes, got dressed in all black and crazy face masks, so nobody knew who they were. The entire grade met in the student parking lot, got 2 huge water grenade for each runner, and filled them all with either Red or Green Kool-Aid or Milk. Then, around 8:30am, they all got in their cars and drove around to the front of the school, with each car having one runner in the passengers seat and filled the rest of the seats with non-running seniors. They all had their cars in drive and with the brakes on, so they could leave if they needed to. At the same time, all the runners got out of the cars, and bolted into the school. Each runner was assigned a room in the school, so they covered every room in the school. The only rooms that were spared were the ones that belonged to really cool teachers. They ran up to the room, sprayed EVERYONE until both of the guns were empty, a teacher had grabbed onto them, or someone started to chase them. Then, they all bolted out of the school, got back into the car they came in, and they sped off and went home, so nobody could really find them. Apparently for the people driving or just chilling in the car, the ROAR of the people when they started getting sprayed was awesome, could have been heard a mile away. I just remember a ton of screaming!! Nobody got caught, ALL the teachers got soaked, and had to sit in their nasty clothes for the rest of the day. I was dating a senior at the time, so I had the wonderful experience of knowing it was gonna happen and i brought a rain jacket to cover me :))))) I still laugh when I think about it and imagine the horrified look on my annoying math teachers face as she's getting soaked with milk and green Kool-Aid, don't really know how anyone could top that. but, it would have to be executed perfectly so nobody would get caught, because even though nobody got caught that year, they did get threatened with losing graduation.
Another good one that the year above me did last week- Fill 1000 dixie cups with ice, go into to school as early as you can, break into the principals office, place the dixie cups EVERYWHERE!!! On the floor, the desk, the chair, so they can't even walk into the room. The ice will melt or partially melt by the time the teacher comes in, and it's hilarious!
My friend at another school did this- Get two sheep, cows, pigs or whatever farm animal, and spray paint a 1 on one of them, and a 3 on the other. Put them on the roof, inside the school, somewhere really noticeable. The teachers or administration will find only 2, but because they are labeled 1 and 3, they will think there is one with a number 2, and go looking for it, but there won't be one! Soooo funny!
My grade is RIDICULOUS, and we have already done freshman, sophomore, and junior pranks. Most of them were borderline illegal, so I imagine our senior prank will probably result in some prison time :)
