In other news, 100% of all available topsoil contains fecal matter. As do your yards. And playgrounds. And toothbrushes if they sit within 8 feet of the commode.
Still nasty, though.
Don't forget Lakes, Rivers, Creeks, Streams and Oceans.
So remember whenever you swim in any of those you're swimming in **** creek!
