How many times have you been in some fieldcraft, rappelling, rope-bridging or fastroping class and the instructor, fresh off the competitive fly-tying circuit, starts barking at the students about "the rabbit comes out of the hole, goes around the tree, and goes back in the hole" and you're left somewhat flabbergasted. "Rabbit? Hole? What the heck is this guy talking about? All I see is a piece of rope and a knot he created like he's Criss Angel."
