I've done a lot of pranks in my senior year, to name a few.
- putting sealfilm over the toilets; it will splash up when you have to go.
- hanging bicycles on streetlights; it takes some effort, but its a good laugh.
- glueing all the locks; no one can enter or leave.
- putting laxo in the teacherslounge coffeemachine; selfexplanatory.
- glogging & flushing the toilets with the a whole toiletpaperrol; we have a new pool.
pfff, these are the ones I most remember.
