Ever noticed how the highest possible z-index gets assigned to embedded Youtube iframes? It cases a real headache if you have a modal popup on the page, as the popup, which should obviously be on top of the page contents, sits underneath the iframe.

<iframe type="text/html" width="520" height="330"src="http://www.youtube.com/embed/videoURL?wmode=transparent"frameborder="0"></iframe>
