I'm trying to use Twitter's Bootstrap css and js modules. Specifically, the twipsy module, which displays a little text message when you hover over a link
blah blha <a href="#" rel="twipsy" data-original-title="Some title text">you probably</a> blah blah #should display "some title text" when you hover over 'you probably'
I copied some of the html from the demo and included twipsy.js in this jsfiddle.net
but when I hover over the link, the text isn't popping up.
