I got a good one, put a sticky note or tape on the bottom of your computer lazer mouse the lazer part so that the mouse won't work, or if you have the ancient ball mouse, then put alot of tape on their cuz if you take out the ball, then it'll be too obvious. GOOD LUCK
ideas-
-tell on him
-when he tattle tales on u say somthing like , that y i never tell u anything
-trick him into telling on u for somethign crazy that u didnt even do
- dont hurt him or anything cause hell just tell on u 4 it
