Several years ago (more than several actually), I was curious enough to open a Jaclyn Smith beauty book. Having seen her on Charlie's Angels (I date myself), I was curious if any tickling references were contained within. In her section on footcare, I hit paydirt. She explained that in applying the pumice stone to the sole that it would tickle like crazy but result in a smooth sole. I didn't quote vebatim, just from memory. Checked on Amazon, her book, "American Look" (1987) is out of print but should confirm my memory if it is in a library (not worth buying for that rememberance).
