The Science of Paper Clips

I discovered today that there is another way to use a paper clip. I always put the paper clip onto the group of papers by putting the smaller loop over the top of the paper leaving the longer loop on the front of the paper. H. told me the other day that I do it backwards. I noticed that one of my assistants does it small loop toward the front also. Who knew? As near as I can tell there is no effectual difference…but it makes me wonder which way is “right,” or most commonly used. Which way do you use your paper clip? J.
