If you've ever been to the monkey house in one of those awful downscale zoos, you know what monkeys - these particular monkeys - are like: They jerk off and fling poo all day, generally using the same hand for both, and they don't do a hell of a lot else, unless there's McDonald's. All day: jerk off, fling poo, jerk off, fling poo, jerk, fling, jerk, fling.Twitter, basically.
