REBECCAFORSCOT (Gradual Decline of a Grand Piano)

I've found huge amounts of graffiti over 15 years of teaching, often in the most bemusing of places (for instance - a 500+ word diatribe against the perceived indignities imposed on child X by teacher Y scratched into the back of a scientific calculator using a compass point) and often involving gymnastically impossible acts that suggest an almost total lack of knowledge of the human anatomy (unpublishable)

But for sheer volume you will never beat Girl 4 Boy.
