We’ve all seen the faux rock that stores a spare house key in the event that you lock yourself out in a pair stained ‘titey whities’.  Well, since burglars have caught onto this in the last, what, 10 years, it’s time to switch things up.  Enter the Sprinkler Hide-A-Key.  I don’t think too much explanation is needed, but in case you’re wondering it can be yours for $6.  Just remember where you bury the darn thing, otherwise you’ll be on hand and knee.
