LONDON — So you want to be a 77kg (170 pounds) weightlifter, eh? FYI: Sometimes things work out as they did for Sa Jae-hyouk of South Korea during the London Olympics on Wednesday:

That thing that looks like a bran muffin under Sa's skin on his right arm would be his elbow, which was dislocated as he attempted a 162kg (357 pounds) lift in the snatch, according to the Daily Mail. He screamed in pain, as medical and team personnel rushed over to assist him at ExCeL arena. It was all quite unsettling.

Video and a photo you can't un-see coming up.

First, here's how it looked when Sa's elbow buckled on the lift:

And now, a selection from Fourth-Place Medal's forthcoming coffee table book, "Elbows Shouldn't Look Like That":

Egads.

Jae-hyouk rallied to win gold in Beijing at the 2008 Games, and was expected to medal again in London. Alas, the only title he's chasing now is likely "Most Gruesome Injury of the 2012 Games."
