Global Orgasm
From the Global Orgasm Wiki article:
Global Orgasm, also known as GORG, was an action originally scheduled for 22 December 2006 to coincide with the end of solstice. The idea was for participants throughout the world to have an orgasm during this one day while thinking about peace in order to emit positive energy to Earth.
Global Orgasm for Peace follows in the footsteps of other mass meditation and prayer events which also claimed to be able to change the energy field of the Earth. The Global Consciousness Project (GCP) measures random numbers and claims that large events that create focused attention can create measurable effects on random number sequences. The Global Orgasm’s organizers hope to create a positive change in the energy field of the Earth that can be measured by the GCP and that might begin a shift away from war as foreign policy.
