This is such an amazing idea. I've already thought of two things it might be useful for: a) No headphone cords when running. b) No headphone cords if you fall asleep (just in case they get wrapped around your neck)
Shoot your alarm clock to turn it off each morning. but wouldn't you have to grab the gun which takes the same time as turning the alarm clock off. and then you'd have to shoot the target when you're half asleep to turn the darn thing off.
