Scrubbing the deck of enlightenment with the wirebrush of examination to remove the seagull feces of disillusionment.
Because the question of, "Why do dogs piss on fire hydrants?" may not be as easy as it seems.
They're marking their territory. That's right Johnnie, you get an "A". Now hurry along and get your associates degree so you can adjust claims or work in a crime lab or whatever.
They do it because they smell other dogs piss. You post hoc ergo proctor hoc spouting brain waste. Of course they do.
But at some point in time there was a dog, possibly visionary, maybe misunderstood in his time, a loner amongst it's peers, who laid aside convention and hiked it's leg at any and every fire hydrant it came across. This, in a rapid and inexplicable succession, led to every dog in existence pissing on every fire hydrant they came across.
If you want to believe that there is some massively linked dog conspiracy and they have communicated this universal 'dogism' to one another, well go ahead. But can this be? Are dogs capable of this highly organized and systematic networking of dogs across the world at large?
Or do they just like to pee on things?
