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.
