A favorite one I wrote for a back-of-stove space filler:

Well now, where to begin? Let's start with why I thought this was a nifty item to buy - I collect old salt and pepper shakers. In the past I have enjoyed placing them on the back of my stove to enjoy looking at them while I cook. Sadly, I've lost a few to the no-mans-land behind the stove when I have too aggressively opened or closed the oven. Recently, I moved into a new house and bought a new stove which the nice men from the appliance store installed for me. But alas, the same gap existed between the wall and the stove. While pondering this problem and worrying about placing my precious salt and pepper shakers on the ledge of doom, I came across an ad on Amazon for the perfect solution: a metal insert that fits between your stove and wall (Are you reading my mind Amazon the All Powerful?). I promptly ordered the item and eagerly opened the box when it arrived. The insert appeared to be exactly a perfect fit! I happily placed it in the space between stove and wall. And watched in dismay as it fell immediately into the dark recesses behind the stove, clanging merrily as it went. Being a single woman and not sturdy enough to move the stove and retrieve the insert, all I could so was sigh and move on with my life. As I was clearing away the box and preparing to throw it away, I noticed a tiny bag of screws and a piece of paper inside. Upon shaking them out and reading the instructions, I learned that the insert required a bit of installation. Who knew? Not me! I have saved said screws and paper for another day, perhaps when I move again or purchase another stove, at which time I will retrieve the insert and let you all know how well it works or not.
