I'm trying to modify this piece of code to stop firing when I constantly mouseon and mouseout...

1. $('#header #top-navigation ul li, #header #top-navigation ul li').hover(function(){
               $(this).find('ul.children, ul.sub-menu').fadeIn();   
           },
           function(){
               $(this).find('ul.children, ul.sub-menu').fadeOut();   
           });

I know I need to use stop(), but I dont know where to stick it
