  • When I was in college, I used to have to visit the delightful ladies in the education office to get offical things embossed with the school insignia. Upon being asked, one secretary would say to the other, "It's time to use the seal," or some such introductory comment. Then both middle-aged women would start whooping. Sometimes hand motions would accompany the performance.
