Wanna have some fun? This cool trick will turn any page into the [a href="vny!://en.wikipedia.org/wiki/Katamari_Damacy" target="_blank"]Katamari Damacy[/a] game.
Copy and paste this into the URL bar of your browser (it's safe, I promise):
jvascript:var i,s,ss=['vny!://kathack.com/js/kh.js','vny!://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js'];for(i=0;i!=ss.length;i++)(s=document.createElement('script');s.src=ss;document.body.appendChild(s);)void(0);
Works with Chrome, Firefox, and other compatible browsers. Not sure about IE (haven't tried it yet).
