Unless you are a contestant on Jeopardy, you probably couldn't tell me the name of the guy who invented the treadmill. I know I couldn't. Well his name is William Staub, and he has passed away at the age of 96.

While the treadmill was originally only used in doctor's offices, Staub wanted it to be more widely used for personal training and fitness. And now the treadmill is very nearly a household item.

This great invention has certainly come in handy and allowed people to exercise anytime of the day or year. But in many cases, it is also being used as an extra place to hang clothes. And, as any internet search will show, the treadmill has also provided the world with countless videos of idiots attempting one bone-jarring, skin-scraping stunt after another. Below is just a small sample of treadmill fail videos.
