I used to work at a post office. My friends and I would always joke about installing a big punching bag to "let out some steam."

We wanted to have one on each corner of the building, so no matter where you were, you could just rush over and punch away. (Did you know that postal facilities have the most anger-per-square-foot than any other building in any other industry? Some insiders blame it on the wandering two-legged coffee holders).

We didn't want to get escorted out of the building (again), so we just kept that idea to ourselves. Anyway, maybe there'd be some money in installing these type of stress-relievers for companies.
