Gents toilet wall graffiti down the years:

"It's no use standing on the seat
The germs round here can jump six feet"

"Seven-Up is good for you - ask Snow White"

"Linda Lovelace has the nicest teeth I've ever come across"

(Imperial College toilet wall, 1969): "Shit hard - it's a long way to the refectory"

(Ratagan youth hostel gents, 1975): "Economy drive - please use both sides of the paper"
