The Clothes Shrinker 5000

It takes you no time at all to find which invention you want to use against him. The clothes shrinker 5000! To anyone who didn't know it would just look like a remote control with a small satellite dish on the end. You know different. You know that it's a carefully calibrated nano ray that shrinks any fabric you point it at. Immediately your mind runs wild with possibilities. Taking a breath to calm yourself, you think for a second and realize that you'll have a lot more knowledge to prepare yourself with if you get a hold of Bradley's schedule.

You sit down at your computer, and in no time you've hacked into the school's portal. That made it easy to simply open Bradley's online planner and see that he jogs every day before class, and has wrestling practice on Wednesday afternoon. Both places will leave him vulnerable to a fairly public humiliation. Where do you strike?
