Oui! Si! Da! Ja! Yes!

Any way you scream it, one group hopes you'll be having an orgasm in the name of world peace this Friday at 6:08 GMT.

At the exact moment of the winter solstice, the world is urged to get busy at the second annual Global Orgasm for World Peace.

People across the world — but especially in countries with "weapons of mass destruction and places where violence is used in place of medication" — are being asked to synchronize their orgasms, according to the group's Web site.

This group session of sexual healing, aka The Big O, is designed to be an "instantaneous surge of human biological, mental and spirtual energy" that organizers hope will reduce levels of violence, hatred and fear around the world during this, the longest night of the year.

Global Orgasm is the brain child of Donna Sheehan and Paul Reffell, co-founders of the anti-war organization Baring Witness, a group of activists who strip to make public peace displays with their naked bodies.
