Why Can’t I Stop Watching This Woman Prancercise? [VIDEO]

Apparently 'Prancercising' is a thing. I had no idea. I watched this video via a friend's Facebook post thing morning, and soon found myself in a hypnotic state accompanied by frequent bursts of hysterical laughter. I have watched this video three times since arriving to my office this morning. I can't stop. Why does Prancercise mesmerize? Would you ever attempt this 'new' form of fitness?
