The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore so it eats it! (It's rather like getting tenure.)
Did you ever want to set someone's head on fire, just to see what it looked like? Did you ever stand in the street and think to yourself, I could make that nun go blind just by giving her a kiss? Did you ever lay out plans for stitching babies and stray cats into a Perfect New Human? Did you ever stand naked surrounded by people who want your gleaming sperm, squirting frankincense, soma and testosterone from every pore? If so, then you're the bastard who stole my drugs Friday night. And I'll find you. Oh, yes.
We are like a bunch of dogs squirting on fire hydrants. We poison the groundwater with our toxic piss, marking everything MINE in a ridiculous attempt to survive our deaths.
