Gods, Id like to know too! I think originally a game was on and I couldnt stop laughing. Compared to American football, it looked like a continuous series of hail-mary passes which I found hilarious. Once I saw a throw-in where a player is lifted, and I couldnt get the image of ice dancing out of my mind, I was irrevocably hooked. Hence my search for explanations that satisfy only when accompanied by jazz hands. Honestly though, I really do like it.
