I found the mack-daddy of all bookmarklets at webgraphics this evening. This just absolutely rocks:
<a href="javascript:var d,h,s;void(d=document);void(h=d.getElementsByTagName('head')[0]);void((s=d.createElement('script')).setAttribute('src','http://www.ashleyit.com/liorean/viewstyles.js'));void(h.appendChild(s));" title="view my css, baby" onmouseover="window.status='take it all off'; return true;" onmouseout="window.status=' '; return true;">Try it and see</a>!
Always nice to see you’re appreciated!
