How modify this Coda Pop Up plugin code to trigger only once?

   This is the Coda Pop-Up plugin from jQuery For Designers blog. It's a great tutorial and I've got it to work beautifully, only for it's application on my website I'd like the effect to be triggered only once and  run through the effect but after it is completed the trigger can't be activated again. With the existing code the effect is triggered every time you mouse over. I've tried messing with the '.stop(true, true)' but not very successful.  Any help will be greatly appreciated!

The code can be seen at this link: 


 $(function () {
        $('.bubbleInfo').each(function () {
            var distance = 10;
            var time = 250;
            var hideDelay = 500;

            var hideDelayTimer = null;

            var beingShown = false;
            var shown = false;
            var trigger = $('.trigger', this);
            var info = $('.popup', this).css('opacity', 0);


            $([trigger.get(0), info.get(0)]).mouseover(function () {
                if (hideDelayTimer) clearTimeout(hideDelayTimer);
                if (beingShown || shown) {
                    // don't trigger the animation again
                    return;
                } else {
                    // reset position of info box
                    beingShown = true;

                    info.css({
                        top: -90,
                        left: -33,
                        display: 'block'
                    }).animate({
                        top: '-=' + distance + 'px',
                        opacity: 1
                    }, time, 'swing', function() {
                        beingShown = false;
                        shown = true;
                    });
                }

                return false;
            }).mouseout(function () {
                if (hideDelayTimer) clearTimeout(hideDelayTimer);
                hideDelayTimer = setTimeout(function () {
                    hideDelayTimer = null;
                    info.animate({
                        top: '-=' + distance + 'px',
                        opacity: 0
                    }, time, 'swing', function () {
                        shown = false;
                        info.css('display', 'none');
                    });

                }, hideDelay);

                return false;
            });
        });
    });
