In minuscule printing between the tiles at eye-level above a urinal: "look up". A few tiles further up was another "Look Up". Then again on the wall above the tiles and in larger print, "LOOK UP". On the ceiling, directly overhead was written, "Look down, man, you're pissing on your shoe!" This received my "Most Creative Bathroom Graffiti" award, but I never knew to whom I should give it.

In a women's bathroom stall, (Back in the days when I was a janitor I got to see a lot of good stuff.) was written: "Adam was a rough draft".

While we are still in bathrooms (and I can't remember how we got here in the first place!) I am reminded of a poster I used to have hanging in my bathroom. It was a Ziggy cartoon. He was sitting on the toilet and looking at an empty wiping paper roll. The thought-bubble over his head said: "Did you ever have one of those lives?" - It always made me laugh for some reason.
