Cubicle Tool: Stress Relievers

It's impossible not to get stressed working in a cubicle. For most, it's a daily struggle. And for many, basic health insurance isn't enough to cover all of the psychotherapy needed to diffuse the stress obnoxious coworkers, idiot bosses, and rude clients put on us every day. Thankfully, handheld stress relievers provide a little comfort in the storm, as we grip, twist, and grab our through trying workdays.

Anyone else have other low budget means of reducing stress in the cubicle farm?
