title: jQuery.getJSON causes "Uncaught SyntaxError: Unexpected token :" for youtube oembed
body: <p>Here is what I'm trying to do:</p>
  
  <pre><code>$.getJSON('http://www.youtube.com/oembed?url=http://www.youtube.com/watch%3Fv%3DB-m6JDYRFvk&amp;callback=?', 
             function(data) { console.log(data) });
  </code></pre>
  
  <p>When curling that URL I get this response:</p>
  
  <pre><code>{
      "provider_url": "http:\/\/www.youtube.com\/",

  <p>But when I try to execute the above code, I get an <code>Uncaught SyntaxError: Unexpected token :</code> (Chrome). It looks like the problem might have something to do with the escaping of the forward slashes, or maybe that jQuery is sending a <code>JSONP</code> request, but the response is pure <code>JSON</code>.</p>
  
  <p>Has anyone else run into this problem?</p>
