Optical Mouse Mess
In middle school, it was super-cool to steal the balls from the mouses in the computer lab. Well, now things have become a mighty bit more advanced, but it can still be hilarious to perform mouse-chief. Just take a small piece of tape and put it over the laser sensor on an optical mouse. It’ll go haywire, causing instant consternation – and plenty of laughs. Just make sure the tape matches the mouse in question. You can always color it in with a pen to make it work.
