    These pranks sounds fun but unfortunately such activities are prohibited at my place.
    How about all the students dress like a Mafia including the Hats covering their half face.

  2. nope says:

  3. Thespacecowboy says:

    So what if the school doesn’t allow Senior pranks. Do it anyway. It would be way more satisfying. But you would have to be smart about it and not get caught (black masks, latex gloves, that sort of thing).

  4. _____TheKiller says:

    turn the front lawn in to a battle ground. with water balloons and burritos as ammo *MWAHAHAHAHA*

  5. sierra says:

    Everybody dress like Hippies, go to the school lobby, play music,sit and have a picnic. Its cheap and pretty fun

  6. Anonymous says:

    We never did a major prank, but we did tons of random spontaneous ones. GermX in water cups, pushing string cheese and meat up the hollow legs of teachers desk legs, switching out the dry erase markers with permanent ones so it was the teacher who did the real damage, zip-tying absolutely everything together, writing insults about teachers on random pages in all the yearbooks for future classes to enjoy… So many more lmao
