How to duplicate function

Hi!
i tried modify superfish.js - superfish menu based on JQuery.
i have this function and work is great
  1.     showSuperfishUl : function(){
                var o = sf.op,
                    sh = sf.c.shadowClass+'-off',
                    $ul = this.addClass(o.hoverClass)
                        .find('>ul:hidden').css('visibility','visible');
                sf.IE7fix.call($ul);
                o.onBeforeShow.call($ul);
               
                $ul.animate(o.animation,o.speed,function(){ sf.IE7fix.call($ul); o.onShow.call($ul); });
                return this;
            }










But if add duplicate

                    sh = sf.c.shadowClass+'-off',
                    $ul = this.addClass(o.hoverClass)
                        .find('>div:hidden').css('visibility','visible');
                sf.IE7fix.call($ul);
                o.onBeforeShow.call($ul);
               
                $ul.animate(o.animation,o.speed,function(){ sf.IE7fix.call($ul); o.onShow.call($ul); });
                return this;
            }
