A guy I used to work with was stationed in Fairbanks, Alaska with the Army. The entryways to the buildings would get very icy from all the foot traffic. Of course, all entry ways were monitored by video. He told me they had a whole collection of people slipping and falling in as they walked into the building. It kept them entertained while on watch.
I admit I laughed at the video but I must admit I am terrified of falling on ice. I fell in the parking lot at work and hurt my shoulder. And I had trouble getting my feet under me because it was so icy.
