Today’s Prolonged Yet Truly Morbid Fact!
The Heretic’s Fork was a torture instrument consisting of two little forks, one set against the other, with the four prongs rammed into the flesh, under the chin and above the chest. A small collar supported the instrument in such a manner that the victims were forced to hold their head erect, thus preventing any movement. The forks did not penetrate any vital points, and thus suffering was prolonged and death avoided. Obviously the victims’ hands were tied behind their back.
Culled from: Torture – Inquisision – Death Penalty

Must be where the expression “Fork You” comes from.
And, “Quit forking around!” 🙂
