"... putting together a paper on the permutation of lyrics..."

I'd love to do that; that's the kind of things we should be spending our days doing. What fun. (Now I have to convince my family that they don't need my extra income for things like jeans and shoes and oil filters and fish food and ... ack, I can't even convince myself. But, maybe I can convince my daughter college is worth it, that it offers the opportunity to write papers like this!)

How did he go about finding some of these things? I can't imagine where the above would have appeared!
