   If you are at a zoo, and a monkey climbs up high in the bars and sticks his thing through the bars, you should move away from the monkey cage. Move in an orderly fashion- don't push, don't rush, don't make it like a Who concert in Ohio. Just move back nice and slow and easy, because that monkey may be having some problems, he may have some hostility towards you. So please- this is just a public service announcement, that's what this is. Just to make sure it's very, very clear. And this PSA is brought to you by: Monkey Tuesday!
