For a few years I've been taking my old running shoes, after they've put in their 500 or 600 miles of training, and using them as casual, everyday, walking-around-in shoes. I recently wondered if perhaps if they weren't suitable for running, they could be potentially harmful just to walk around in. Anyone have any thoughts?
Please feel free to make stupid, humorous comments.

I guess it depends on how bad your feet smell. You could be a hazard to all people in your time zone. Ok, weak joke, but you asked for it. Seriously, it depends on your footstrike. If you are very neutral you should be fine. If you can set your shoes on a flat surface and notice a pronounced lean in either direction, then it could be trouble even for casual wear. The impact would not be as severe when compared to running, but if the shoes are no longer supportive or are heavily pronated or supinated then you are putting unnecessary stress on your knees, hips and back.
