Here at Google headquarters, when you use the urinal you get to read Learning on the Loo, which is a one-page document placed at eye level right in front of you.

Unfortunately both of them are pretty long– a full page– which makes them hard to read in one session. I suppose you could drink a lot of water and kind of “save it up” until you really have to go, and that way you’ll be able to get through the full article.
