I have a sledgehammer and a smoke detector that is facing it's demise. This is no ordinary smoke detector. This particular one chirped (that sound when the battery's going dead)............in my garage/internet smoking lounge..........for perhaps a year. Yes I said a year. It wasn't until yesterday when my x-roomie came for a visit and said "what is that noise?" that I realized it was still doing it. Seriously. And before the day was over she had found that smoke detector........in a box, with pictures.
I either drowned out the chirping sound with iTunes or I developed a tick and no one bothered to tell me.
