Yesterday morning at work I was using this contraption called a burr bench, which takes newly milled metal parts and tumbles them in wet ceramic pellets to smooth the edges. It's like a top-loading washing machine, except smaller, and it vibrates like crazy.
While I was standing around trying to look useful, one of the other guys that works there came up to where I was. Then he said, while gesturing toward the burr bench, "There was this guy that used to work here. I'd be over on the other side and he'd be here. When I'd walk over, he'd be standing up against this with his nuts on top of it." Now when I use this machine I won't be able to think of anything else.
