Hey ,
When I was in boarding school, I remember pulling a number pranks, from Vaseline on door knobs so no one could get in (or out), saran wrap on toilet seats (sure you can imagine what happens here), to short
sheeting beds (look it up, if you don't know this one.)
GO BELOW THE IMAGE FOR A VIDEO FULL OF PRANKS YOU CAN PULL!
Hugs,
Melissa
