If you’re stuck at your desk and mad at your boss, wife or the world in general, then don’t do something stupid. Instead, put the Stress Buster Desktop Punching Ball on your desk. It comes with a heavy-duty spring that brings the ball swinging back for more pain every time you punch it. The pump is included, and it has a neat stand that keeps the whole thing balanced even if you’re pretending to be Mike Tyson (no biting allowed).
