And the words of the prophets are written on the subway walls and bathroom stalls.

With apologies to Simon and Garfunkel, I was just in the mens' room at a quick service restaurant for a quick service pee. And the little, plastic perforated thing at the bottom of the urinal designed, I suppose, to keep cigarette butts out of the drain had an advertising message on it.

"Swisher. A healthy respect for hygiene."

I know I haven't a media background but I can't quite comprehend the value of urinal advertising.
