Eamonn Kilbride, 46, just finished doing the quarky "Gangnam Style" dance at an office Christmas party when he collapsed to the floor and died of a heart attack.
The U.K. man was doing the energetic dance moves at the Thwaites Brewery office party, where he worked as an IT manager, at Lancashire's Whitehall Country Club when he complained of chest pains. His wife, Julie, was with him and tried to desperately revive him with CPR.
"We were having a fantastic time at the Christmas party and Eamonn had just finished dancing to 'Gangnam Style,'" she told the Daily Telegraph.
Paramedics tried reviving the father of three as well, but he was pronounced dead at the Royal Blackburn Hospital.
This may be the worlds first death by "Gangnam Style."
