This book is just what it looks like, a collection of bathroom graffiti collected by a scholar with a lot of time on his hands. It makes me kinda sad, cuz I can't remember the last time I read anything clever or witty on a bathroom wall. Just the same old "For a good time call. . . " and "Here I sit broken-hearted. . . " but back in 1967 you could find a great graffito like:
"A toast to a German virgin -- Goesintight!"
"Stand up close. The next man might have holes in his shoes."
"Don't write on our walls. We don't shit in your notebooks."
