How many more lives must "Gangnam Style" ruin?

46-year-old Eamonn Kilbride of Burnley, Lancashire, England is an IT manager at the Daniel Thwaites Brewery.

On Saturday night, he was at the company's Christmas party at a country club, and "Gangnam Style" came on.  Eamonn got up on stage and started doing the "Gangnam Style" dance for everyone, and people LOVED it.  Then he COLLAPSED.

He was rushed to the hospital . . . where he was PRONOUNCED DEAD from acute heart failure.

And yes, the minor physical exertion from "Gangnam Style" was the cause.  If you're not used to exercising, even pretending to rhythmically ride a horse might not be good for your heart.

Eamonn had a wife and three kids.  His wife says Eamonn, quote, "was always the life of the party and loved dancing."
