If you use the HTML5 player for YouTube, you can use the UI to increase the playback speed to 1.5 or 2.0.  While I do like my talking heads to talk a bit faster, I don't like them to take a full 50% faster.  This bookmarklet will allow you to set the playback speed to an arbitrary value.

javascript:%7Bvar%20v%3Ddocument.getElementsByTagName(%22video%22)%5B0%5D%3Bv.playbackRate%3DparseFloat(prompt(%22Playback%20rate%3F%20%5B%22%2Bv.playbackRate%2B%22%5D%22))%3B%7Dvoid(0)%3B

Here's the easier to read version of the same code:


{
  var v = document.getElementsByTagName("video")[0];
  v.playbackRate = parseFloat(prompt("Playback rate? ["+v.playbackRate+"]"));
}
void(0);

Drag this link to your bookmark bar to create a bookmark you can use on YouTube.
