How can I get my javascript function randomly select one function(slideshow), execute it, then repeat?

I have a javascript code for replacing a html <div> that contains an image in it, so it becomes like a slide show. I have six of these slideshows on the page, and I need them to randomly change maybe switch image 3 then 6 then 2 and ect.

$(document).ready(function(){
     SlideShow6();
});

function SlideShow6() {
    $('#slideshow6 > div:gt(0)').hide();

    setInterval(function () {
        $('#slideshow6 > div:first')
        .fadeOut(0)
        .next()
        .fadeIn(0)
        .end()
        .appendTo('#slideshow6');
    }, 0000);
}

The time over here at the end is 0000 (0)seconds. Becuase I need the timer to have a 2000 (2)second pause before picking a random slide to slide. I tried my script with this:

var funcs = [];

funcs[0] = function() {
    $('#slideshow6 > div:gt(0)').hide();

    setInterval(function () {
        $('#slideshow6 > div:first')
        .fadeOut(0)
        .next()
        .fadeIn(0)
        .end()
        .appendTo('#slideshow6');
    }, 0000);
}
funcs[1] = function() {
    $('#slideshow5 > div:gt(0)').hide();

    setInterval(function () {
        $('#slideshow5 > div:first')
        .fadeOut(0)
        .next()
        .fadeIn(0)
        .end()
        .appendTo('#slideshow5');
    }, 0000);
}

// and so on six times... then...

$(document).ready(function(){
    var rand = parseInt(Math.random()*funcs.length);  
    funcs[rand]();
    setTimeout(arguments.callee, 2000);
});

It becomes really wierd, it selects my functions randomly but it executes the slideshow a unlimited number of times and before soon all six of them are on and going. Maybe because of the 0000? I need them to switch image one by one.
