<script type="application/javascript;version=1.8;e4x=1"> ;)

Oh, ja!

function rot13 (x) {  
 var ao = 26, start = [start for each (start in [65, 97]) if (x >= start && x < start + ao)][0];  
 return start ? x + (x - start >= 13 ? -1 : 1) * 13 : x;  
}  
alert([String.fromCharCode(x) for each (x in [rot13(x) for each (x in [c.charCodeAt(c) for each (c in "Clguba va WninFpevcg!")])])].join(""));
