The Sound of shoulders snapping

Watching some quality CBC Olympic coverage on the TV this eve, 4am in Greece, and they (CBC) featured a Sounds of the Olympics segment, which was a real treat, the most incredible sound coming from a weight lifting competitor who just barely got the bar above his head until his left arm kinda wobbled and gave way, collapsing the whole routine and the athlete himself. And the announcer confirms that the unbelievable, cartoon-like snap we all just heard when the arm gave way was in fact the pop of breaking bones. Oh man, wow.
