[jQuery] Slide down menu shaking unexpectedly. ha wow. wtf is it doing

[Chris J. Lee]

I'm having problems with the slide down. It's severly delayed. i'm not
an expert at jquery at all. If it isn't already obvious.

I'm trying to program a text link to slide down a menu from above.
here is the code:

        $("#activate").bind("click", function() {
                $(this).toggle(function(){
                        $("#activate").text("- HIDE ").show("slow");
                        $("#dropdown").toggle().show("fast");
                        }, function() {
                        $("#activate").text("+ SHOW").show("slow");
                        $("#dropdown").toggle().hide("slow");

                });
        });
