Tic-tac-toe at men's urinals

Primary purpose of a tic-tac-toe game is make strategic moves such that the player forms a straight line (horizontal / vertical / diagonal). The opponent moves in such a way to deny you the opportunity to form such a straight line.

But why am I talking about tic-tac-toe at men's room? Because my common sense says that the men's urinals is definitely not the place to complete a tic-tac-toe line.

It made me to ponder if this is spoken in a wider forum. A little search in google took me to this website that detail about the very issue. 

On further research I landed up at International Center for Bathroom Etiquette (http://www.icbe.org) who's logo simply captures the essence of this article :)

We are a long way to go to follow this in a world where people queue up right behind your rear-end and wait for their chance!
