Don't repeat yourself; if you're repeating yourself, you're doing it wrong.

// BAD
if ($eventfade.data('currently') != 'showing') {
    $eventfade.stop();
}

if ($eventhover.data('currently') != 'showing') {
    $eventhover.stop();
}

if ($spans.data('currently') != 'showing') {
    $spans.stop();
}

// GOOD!!
var $elems = [$eventfade, $eventhover, $spans];
$.each($elems, function(i,elem) {
    if (elem.data('currently') != 'showing') {
        elem.stop();
    }
});
