Rather surprisingly, this toy has become all the rage in my office. Basically, two to four people stick their fingers into little holes and wait to see which one will get a pretty powerful but safe low-voltage shock. At first, the reaction is screaming and groaning, but that quickly turns to laughter. Then we started coming up with variations — All Girl Shocking Roulette, Shocking Roulette for Money, etc. My favorite is Who Can Withstand the Shock Without Any Change in Expression or Reaction. I own that sucker.
