Toilet Paper Holders
It's happened to everyone at one time or another. The roll falls of a loose holder, or the roller gets so rusted it won't turn properly, so you keep breaking pieces of fluff off - just large enough to wipe a mouse. If it's someone else's bathroom and you are the guest, its a forgivable offense. But if you're putting up daily with a renegade roll that just won't cooperate no matter how you twiddle with it - maybe it's time to buy a brand new one!
