Having worked in a cubicle office where Nerf battles were a frequent occurrence, let's just say that it would be the death of productivity. And that's before you lose co-workers to ritual office battles.

Hey, was bug #4587 fixed yet?

"No idea. That was Carl's task, but he died without honor last week. So probably not."

Also the idea of getting through every code review with a bat'leth just sounds exhausting.

It would be great for business! You'd only have to pay salaries to the survivors.
