[jQuery] Code evaluation

[jQuery] Code evaluation


I have some jquery code that does what I want it to do but I was
wondering if I could get some input/ suggestions/ opinions on how it
could be better.
Thanks for your time!
here is the code:
jQuery.fn.swapFade = function() {
    if (this.is(':hidden')) {
        this.fadeIn('slow');
        } else {
        this.fadeOut('slow');
        }
};
$(document).ready(function() {
        $('p').hide();
        var hash = {'one': 'a', 'two': 'b', 'three': 'c'}
        $('a').hover(function() {
            $(this).fadeOut('slow')
            $(this).fadeIn('slow');
            $('p.' + hash[this.className]).swapFade();
            return false;
        });
});
