Imaginary Profit Margins

Teaching the basics of Excel is always a nice respite from actually working with the program, and lecturing with my laptop on an overhead projector takes me right back to the Kenan-Flagler days, except the bus shelters outside have "Mbeki Spears Zuma!" headlines tacked up instead of Clef Hangers announcements and RU schedules. I'm hoping to get as many interns as possible close to an intermediate level before they leave, and most seem keen so far, though they don't look it here.
