Some jokers once showed me the worlds fastest way to tie a bowline. They used both hands and their arms. They through a loop into the rope while holding the rope at each end of the knot. Then fliped it a couple of times and drew the ends tight. Bingo! A dragon bowline. "Dragon?" I said.
They would respond, "Yeah, draggin'. Cause all it is good for is dragging on the ground behind you."
The point of the joke was that this method of tying the bowline was only good for a loop on the end of a line (to be dragged behind). Because this style of tying the knot could not be implimented if you were actually tying, attaching the rope to something.
Gary, that's not how I do it. I make a regular bowline knot, big loop or small loop or whatever. I've never seen the dragon bowline, but sounds like a good stunt, even if it isn't good for anything.
Pat, since you mentioned tying it behind the back, I had to try it. First time, 3 seconds flat. Tying a bowline is the only thing I do well.

Had to get lots of practice at it when we were sailing our cruising boat many years ago. Seems like a lot more knots are used (and used more often) on a big boat than on a beach cat.
