My favorite YouTube oddity: If you hunt over the CSS the site downloads on, IIRC, every page; you'll eventually come across this selector:<p><pre><code> ytd-watch-metadata[video-id=QrGrOK8oZG8] h1.ytd-watch-metadata {
color:#e6d140;
font-family:Georgia,serif;
font-size:250%;
font-variant:small-caps;
font-weight:normal;
transform:skew(-5deg,0deg);
text-shadow:1px 1px #000,1px 1px .1px #000
}
</code></pre>
A selector that appears to be referencing a very specific video ID; as far as I can tell, the only video in the billions of videos on YouTube to receive this treatment (at least, in terms of a "css selector with video-id in it").<p>The video: Adult Swim's "Too Many Cooks" skit (<a href="https://www.youtube.com/watch?v=QrGrOK8oZG8" rel="nofollow">https://www.youtube.com/watch?v=QrGrOK8oZG8</a>)
