This is kinda dumb, but oh well, help with revenge!!!?

okay this is sorta dumb but w.e lol. Kk my friend threw a pop tart at me as a joke, and then tried me in the hall (like joking around not cuz he hates me or anything, were just having fun lol) but i want to get him back, because usually i don't. so any good ideas on how to get him back, nothing too drastic tho lol
