One of the threads about bird feeders made me think of this. How do you keep squirrels out of your feeders? When I lived with my parents, they tried all sorts of things. The most fun was a little rack on the bottom of the bird feeder, that would spin madly around as soon as any weight was put on it. It sure was fun watching the squirrels hang on for dear life as their world spun around them, then scamper away as if drunk because they were so dizzy. Another method that my brother tried was to sneak up on the invading squirrel, grab it by the tail, and fling it off toward the woods. Don't try that one. He ended up with a handful of bushy squirrel tail, and the poor squirrel couldn't even balance enough to walk on thin branches anymore. Tail just popped right off.
