One night, my wife (then girlfriend) heard me open the door and wander out into the yard at my duplex I was living in to find me pissing in the yard. I was quite imbibed, and she says something like "what the hell are you doing pissing outside?". Then, in my quick witted math brain, I started spewing out numbers...
-"So...there are 350 million Americans...roughly half male."
-Say there are 50mm men aged 18-50, and of that, 1/2 of them like to have a few beers on Friday and Saturday nights.
-Now, the American male will take a piss 4-6 times per night while they're having a few beers, so let's say 4.
-It's roughly 1.6 gallons per flush, but let's say 1 gallon to be conservative.
-So, if our 25mm American males piss 4 times per night when they're drinking...at 1 gallon per flush...That's 100mm gallons of water every friday and saturday night of the year.
-So...Multiply 200mm x 50, because even the most fervent consumer usually has 1 or 2 weekends off per year, and my plan will help America save 10bn gallons of water per year....and that's just on the weekends!!!!!!
She wasn't amused, or impressed.
