Senior pranks are one of the staples of American colleges. While the biggest ones, like pretending to crash a car into the side of a building, are typically saved for the end of the year, individual students take it upon themselves to pull off smaller tricks throughout their time at school.
Take Twitter user @OscareWilde as an example. Several years ago, they were gifted one of those massive pencils that are absolutely useless for anything other than a gag gift. Unsurprisingly, it gathered dust in a closest for years while they tried to find a use for it.
