With exams wrapped up and university acceptance letters rolling in, high-school students across the country turn their attention to more nefarious deeds: Graduation pranks.
June is the month of Saran-wrapped cars and condom balloons, a time when livestock run loose in the hallways. For school principals, it can be a stressful time of year. Political correctness, safety-conscious parents and fears over legal liability leave little room for a sense of humour.
Earlier this month, a pot-bellied pig was found napping outside the cafeteria at Belle River District High School, outside Windsor.
The pig became a celebrity amongst students and a social-media sensation, but animal-welfare advocates were less impressed.
Terry Lyons, a superintendent with the Greater Essex County District School Board, said the prank met his threshold for acceptable behaviour, provided the pig wasn't stolen (its owner still hasn't been found, and its provenance remains unclear.)
Principals need to identify "the key players," he said, the students who are the most likely grad prank perpetrators and then lay down three rules:
"Whatever's done has to be in good taste, no one gets hurt and you have to be able to take it down."
The Globe and Mail has assembled a range of this year's pranks, ranging from the inoffensive snake-in-a-toilet gag to the more controversial exploding vending machine. Which ones cross the line? You be the judge.
