The group was founded on April 27, 1996. Its name comes from the film Monty Python and the Holy Grail, in which plague victims are thrown into a cart and hauled off to be buried. A man being given up as a corpse by his family protests that he is "not dead yet!"
In 2004 NDY protested the removal of Terri Schiavo's feeding tube. They also protested the movie Million Dollar Baby, in which the injection of an overdose of adrenalin to euthanize a suicidal quadriplegic woman is depicted as a rational and compassionate act. The group has been highly critical of utilitarian philosophers such as Peter Singer of Princeton University. Coleman has called Professor Singer "the most dangerous man on earth" and accused him of advocating genocide.
