[jQuery] passing this reference to setTimeout()

[ekallevig]

I'm using jQuery.hover for a dropdown menu and I want to add a slight
delay to mouseOut functions but I can't figure out how to pass the
jQuery(this) reference into the setTimeout() function... can this be
done?

ex.

jQuery('li.drop').hover(
        function(){
                jQuery(this).addClass('show');
        },
        function(){
                var t = setTimeout( function(){ 
jQuery(this).removeClass('show'); },
1000);
        }
);
