Jonny Noose

My thinking was that perhaps "Jonny Noose" is a nautical term for a type of knot, like "Buntline Hitch", or "The Monkey's Fist", but I can't find any references that mention such a knot.

It was a noose I saw while working on the short lived TV show "Jonny Zero". I couldn't think of a better title. I had seen so many crazy things that day, at the Brooklyn Navy Yard. I'm not supposed to have a camera on set, so I had just a few seconds to get this right & hurry a shot.
