Well, the moment you put that to your ear you will become a pisshead
Brings to mind... Remember this commercial

As long as no one has used the toilet without flushing, the water in the toilet is so clean you can drink it.
Actually, a toilet as a lot more cleaner than a work desk, keyboard, kitchen bench...you name it. Even your urine is drinkable as long as it's fresh and hot. In the old days, when they got hold on a bottle of liquor in the prisons, one person drank it, pissed it out and the next person drank the piss, pissed it out and and so on...since it still contained alcohol.
Somehow people immediately think about germs and **** when they hear the word "toilet", but there are far more scary things you put your hands and face in..all the time, everyday.
I recall a guy in the next urinal having a full blown conversation on his mobile whilst taking a leak..! I mean, what was wrong with guy? Was he so important that he couldn't ignore his phone for the 30 seconds it take to have a leak..!
The water in the tank is clean enough to drink. However, flush or not, unless you disinfect the toilet bowl after each use, I would not necessarily consider the water in the bowl to be safe to drink.
I agree, although urine will be sterile, the water even after flushing won't be free from bacteria. Bleech will kill it if you had one of those bleech release thing with every flush. But with that much amount of bleech, would you really want to drink that water?
