About 10 years ago I was working a summer job in a meat factory and one of the line workers got his pant leg caught in one of the belts and it pulled his foot into it, twisting it around more than 180 degrees. The worst part is he had to sit there for almost 20 minutes while they worked at getting his foot out because it got caught so far into it. His face was so pale, I'll never forget the look of it.
