I am an ardent recycler. I would like to think that it works. I don't know whether it does or not.

I don't like rats, but there's not much else I don't like. The problem with rats is they have no fear of human beings, they're loaded with foul diseases, they would run the place given half the chance, and I've had them leap out of a lavatory while I've been sitting on it.
