How do I duplicate item when using jquery sortable?

I am using this method http://jqueryui.com/demos/sortable/#connect-lists to connect two lists that i have. I want to be able to drag from list A to list B but when the item is dropped, i need to keep the original one still in list A. I checked the options and events but I believe there is nothing like that. Any approaches?

Erez' solution works for me, but I found its lack of encapsulation frustrating. I'd propose using the following solution to avoid global variable usage:

$("#sortable1").sortable({
    connectWith: ".connectedSortable",

    helper: function (e, li) {
        this.copyHelper = li.clone().insertAfter(li);

        $(this).data('copied', false);

        return li.clone();
    },
    stop: function () {

        var copied = $(this).data('copied');

        if (!copied) {
            this.copyHelper.remove();
        }

        this.copyHelper = null;
    }
});

$("#sortable2").sortable({
    receive: function (e, ui) {
        ui.sender.data('copied', true);
    }
});
