With most unwise challenges, you can usually see what the intent was, and where it all went wrong. With this face-first dive from Argentina over the weekend, your guess is as good as ours.

Argentinos Juniors' Gaspar Iniguez went directly into the feet of his opponent, resulting in injury and insult: He lost three teeth, but gained a yellow card. If I were him, I'd be most upset about the opponent rolling around in mock pain after stubbing a toe on my face.
