Recently I have seen several TV commercials about a magnetic
flashlight that the seller claims will, "Stick to any metal
surface." Don't they know that aluminum, copper and brass are
metals and that magnets will not stick to them?

When I am in the kitchen, I often kick one of my cat's balls.
After I kick it, he will sometimes play with it for a few
seconds to several minutes. His favorite are the ones that
rattle. He'll play with any ball that makes noise.
