Dang, that reminds me of a time when I was working nights at a video game arcade while in grad school. I noticed a co-worker's finger was swollen and pale from a too-tight wedding ring. He was a slow fellow and didn't understand the urgency of getting the ring off. After much teaching him about the human circulatory system, he promised that he would see about it the next day, and he did. He had to have it removed; it was too swollen to slide off.
