From the website:
A truly electrifying game of chance! Select the number of players, put your finger in one of the four slots, and let it "spin." Lights and sounds start out fast and gradually slow down (just like a roulette wheel) to prolong the tension. When the sound stops, someone gets the shock of their life! Everyone else gets a big laugh! Victims are electronically selected at random. You never know who will be next. Great for parties. Includes 3 "AA" demonstration batteries. Not recommended for wimps or cowards!
Ooh, I hate static electricity, so I'd probably hate this game: http://www.prankplace.com/shock.htm
I wonder how long it's going to be before someone tries sticking their Linus into one.
