Showboating before you get into endzone.

Having now watched the clip Tiberius posted I have to call giving a penalty ridiculous in that case. He stuck out his hands for a few miliseconds, he was so quick I didn't see it at normal speed, only during the slow mo.

@Brian, that wasn't the player getting ahead of himself. He had a good hold of the ball, you often see rugby players running at full tilt with the wall held away from the body, especially going into a tackle, either to ensure the tackler doesn't rip the ball, or to offload the ball before the tackle is completed and a ruck is formed.
