i secretly duck tape things around my house and school to the walls or under desks, people don't know its me but when they realize its gone i laugh historically.(they always do find it and if they dont i tell them where it is, im not that cruel hearted.)
When I was in high school, I once superglued my teacher's tape dispenser to her desk. A few days later, she went to pick it up, discovered it was stuck, yanked really hard and got sand everywhere.
I actually look back on that and feel
really bad, that was pretty shitty of me. I was a pretty shitty person in high school though. So, at the time, I actually almost pissed myself laughing.
But don't be mean like that, all you youngin-folks.
