Ivan Pavlov's Laughter Bell

Origin
Ivan Pavlov was a Russian psychologist. He became famous for his work with his dogs, illustrating the powers of classical conditioning. He discovered that with time, a being may become trained to illicit a response by the application of a stimulus. In the case of the dogs the stimulus was a bell that announced feeding time. The response was that the dogs would drool in preparation of the food. Even when there was no food to present he was able to make the dogs drool by ringing the bell. It has been discovered that classical conditioning may be effect, but it must be meticulously maintained in order to keep it working.

Effects
When the finger bell is rung it causes whomever who hears it to start laughing hysterically. The victims will be unable to stop laughing until eventually they die from suffocation.
