First case I've heard of where people danced to death. Also, there is a link to an article about a laughter epidemic in Tanzania in the 60's. I put them both together and was reminded of the man who laughed himself to death watching The Goodies.
On 24 March 1975, Alex Mitchell, a 50-year-old bricklayer from King's Lynn, England, had died laughing while watching the Kung Fu Kapers episode of The Goodies, featuring a Scotsman in a kilt battling a vicious black pudding with his bagpipes. After twenty-five minutes of continuous laughter Mr.Mitchell finally slumped on the sofa and expired from heart failure. His widow later sent the Goodies a letter thanking them for making Mr.Mitchell's final moments of life so pleasant.
I've heard of a man who died because of laughing when watching Pythons. Can't remember what actually did he watch.
I usually imagine my own sounds with it, like `tjunk, tupdieyupdiedee` aaa enemy spotted, ratatatataboom
Man this sounds like something out of Monty Python... how bizarre!
