Sprinkler Hide-a-Key

The "sprinkler" hide-a-key gadget is definitely an afforadable stocking stuffer, at only $3.99 plus shipping. It's 3.5 inches high by 1.3 inches in diameter, and looks like a regular sprinkler head. Of course, it might only be useful if you happen to have built-in sprinkler's in your yard already, but you could actually still hide this pretty well in a flowerbed if you wanted. It just depends on how forgetful you are with your keys! I think I've only locked myself out of my house once....
