It's log, it's log, it's better than bad, it's good!

What exactly is the thought process behind leaving a log in the bowl? Is it conservation? "Save water, Do not flush until bowl is brimming with shit.". Is it pride? "That is the most perfect turd my ass has ever created. It would be irresponsible to hide it from the world.". Is it a preventative measure? "Do not drink, this bowl of water is for poo, see?". Is it amnesia? "Where am I? Is this bowl of shit supposed to be here?". Protest? "Look at this dookie and you'll know how I feel about society.". Paranoia? "If I flush this down, they can trace my DNA from the sewers and know I took a dump.". Or is it pure apathy? "I could pull that little metal lever so the next person doesn't have to look at my defecated breakfast.... fuck it. Seems like a hassle."
