American humorist Ze Frank posted How To Dance Properly at his website in 2002.
I laughed almost to the point of injuring myself when I first saw it, and I mentioned it in my 2008 blogpost Top 3 amusing go-go videos.
The website is now defunct but the Internet Archive captures of the page still enable clicking on the panel of 10 dances.
It is initially a bit slow to load but you can also sample it through Harsh Singh's YouTube video of a 35-second click-through of all the dances.
