One of the highlights of the 2012 Olympics was the diving. There was stiff competition that year, especially in the preliminary rounds, and all the athletes were killing themselves trying to look as graceful as possible while tumbling through the air. How do we know? There's something on each diver's face that just reads, "This stunt is kind of difficult to do."

These competitors may look like elegant swans from a distance, but when the camera gets right up close for those slow-motion instant replays, not one of them is capable of hiding the pain in their faces.

If diving isn't the one event you're looking forward to watching during the 2012 Olympics, it will be after you're done browsing through this gallery of all the best diver faces.
