EDIT: This is now dead because apparently the makers of it no longer want our odors to be gone.
Quick, name something that smells worse than cat urine. BEEEEP, time's up and you failed because that was a trick question. You can't possibly name a worse smelling aroma and yet it seems that far too many households out there are plagued by it. Enter this free Odor-b-gone sample. Heck, I'm not even going to sign up for it, but instead discreetly have a few samples sent to select neighbors of mine. Maybe then they'll get the hint!
