The Snore Stopper is worn like a wristwatch, sitting there peacefully until it hears the dulcet tones of your husband's "oink, oink, wheeeeeeew" in the night. It then zaps his wrist, prompting him to change his position and free up his breathing passage. It costs only $59.95, and makes for a great gag when you "pretend" to snore into it, making him flop around like a freshly caught trout.
My friend's father had one of these a long time ago, where you set the intesity of the shock. The problem was that you eventually become desensitized to the shocks... leading you to increase the intensity. My friend says his father ended up getting a burn on his wrist. Of couse we were young teenagers at the time... so this is probably an exageration.
