Kathy, stories of pranks like these always shock and amaze me. I've never been on the receiving or giving end of any such shenanigans. Nor, have I ever seen such pranks being pulled. I'm not complaining, mind you. Though your story has a youthful whimsy of fun about it, I'm obviously not a prankster!
You definitely have wonderful memories of your college days. Maybe, I needed to be more carefree??
