DieHelvetica.js

var fucker = 'helvetica neue',
   	allElementsArr = document.querySelectorAll('*');

for( var i=0; i < allElementsArr.length; i++ ) {
    
    var element = allElementsArr[i],
    	fontStack = getComputedStyle(element)['font-family'].toLowerCase();    
    
    if( fontStack.indexOf(fucker) !== -1 ) {
        var newStack = fontStack.replace(fucker, 'fuck');
        element.style.fontFamily = newStack;
    }
    
}
