That’s right: the key that turns off the alarm flies away and you have to go get it in order to make the damn thing shut up.
I could use something like this, actually. As I’ve mentioned before, the alarm clocks for the deaf that come complete with a bed shaker? Slept through one. Also, in high school, I would have four alarm clocks scattered throughout the room with furniture between me and them. One time I actually turned all four off and went back to bed without remembering doing so.
