senior pranks, any good ones? Options

[misoshiru]

so what pranks have your previous seniors pulled? our school has had some really lame ones...for example, last year, the seniors broke the dress code as their senior prank . but i've heard and thought of some pretty awesome ones:

- at my friend's old school, once the seniors set loose 3 pigs in the school and had numbered on the pigs 1, 2, and 4. as a result, the school faculty spent days looking for pig #3...which conveniently did not exist.

- seniors saran-wrapping the toilet seats.

- pulling off a fire alarm every period of the day (i think i read this somewhere)

- setting loose a whole flock of chickens in school, while playing "old macdonald had a farm" on repeat over the PA system...except changing the lyrics to having to do with chickens.

Was going to make one, but searched. What we're doing this year at my school (Sally, you snitch and I'll hunt you down. I know where you live. And of course, I don't know if these are actually going to happen..):

- Moving security golf carts onto the awnings.
- Painting windows black.
- Jello-ing the pool (this is going to fuck up the filtration...)
- Messing up this one teacher's room because he has OCD.
- Getting a cow up to the second floor (because cows can't go down stairs)
- Smearing vaseline on tables/door handles or putting condoms on door handles.
- Putting onions into the ventilation (because this one teacher everyone hates is allergic to them).
- Making tabloids (as a counterpart to the school paper).
- Moving tables onto buildings.
- Putting tires on the flagpole.
- Saran-wrapping the entrance to the teachers' lot.
- Switching all the room numbers around.

Our school has no hallways. D: It's kind of hard to top "'05 SUCK IT." I admit, that was pretty fucking good.

Any new ideas?
